New High Accuracy Current Sense Amps Compatible with Both Negative and High Voltages

　　ROHM has developed a new lineup of high accuracy current sense amps – the BD1423xFVJ-C and the BD1422xG-C. They are qualified under the AEC-Q100 automotive reliability standard. The BD1423xFVJ-C series, offered in the TSSOP-B8J package, supports input voltages up to +80V, making it ideal for high-voltage environments such as 48V DC-DC converters, redundant power supplies, auxiliary batteries, and electric compressors. The series includes three models with different gain settings: BD14230FVJ-C, BD14231FVJ-C and BD14232FVJ-C.　　For lower voltage use cases, the BD1422xG-C, available in the compact SSOP6 package, supports input voltages up to +40V. This makes them suitable for automotive applications requiring space-saving designs, such as current monitoring and protection (overcurrent) in 5V/12V power supply networks used in body and drivetrain domains. Like its high-voltage counterpart, this series also consists of three different gain options: BD14220G-C, BD14221G-C and BD14222G-C.　　In recent years, alongside conventional 5V/12V power supplies, the automotive market has seen a growing adoption of 48V systems fueled by the rising popularity of electric vehicles. Furthermore, as vehicle functionality becomes more advanced, the need for precise monitoring and control across a wide range of applications continues to increase, placing a greater importance on high-accuracy current sensing.　　A current sense amp indirectly measures the current flowing through a circuit by amplifying the miniscule voltage drop across a shunt resistor. The amplified signal is then sent to an ADC or comparator for system control and monitoring. ROHM’s automotive-grade current sense amps meet market demands by leveraging proven analog expertise. This enables high-accuracy current sensing with compatibility for both negative and high voltage environments, contributing to improved safety and reliability in automotive applications, particularly electric vehicles.　　These new products achieve greater space efficiency by integrating most of current sensing circuitry, typically comprised of an operational amplifier and discrete components, int o a single package. As a result, current detection is possible by simply connecting a shunt resistor. The devices also feature a two-stage amplifier configuration, consisting of a chopper amplifier at the input and an auto-zero amplifier at the output. Internal resistor matching for gain setting ensures stable, accurate current sensing (±1%) while minimizing the effects of temperature variations.　　Furthermore, current detection accuracy is maintained even when an external RC filter circuit added for noise suppression, significantly reducing design complexity and development time. Additional features include -14V negative voltage tolerance that supports back electromotive force, reverse connection, and negative voltage input.　　Going forward, ROHM will continue to deliver optimal solutions that contribute to higher precision and enhanced reliability in automotive equipment.　　Application Examples　　• BD1423xFVJ-C (for 48V systems): Redundant power supplies, auxiliary batteries, DC-DC converters, and electric compressors, and the like　　• BD1422xG-C (for 5V/12V systems): Body DCUs (Domain Control Units) / ECUs (Electronic Control Units), etc.　　Terminology　　AEC-Q100 Automotive Reliability Standard　　AEC stands for Automotive Electronics Council, a reliability standard for automotive electronic components established by major automotive manufacturers and US electronic component makers. Q100 is a standard that specifically applies to integrated circuits (ICs).　　Shunt Resistor　　A resistor connected in series in the current path to detect the current in the circuit by measuring the potential difference across it.　　Chopper Amp　　An amp circuit designed to minimize signal offset and noise, primarily used for accurately amplifying low-frequency and weak DC signals.　　Auto-Zero Amp　　An amp that automatically compensates for offset voltage (unwanted noise and errors) by continuously sampling and correcting it during operation. This ensures high signal accuracy, making it ideal for applications that demand ultra-precise measurement and signal processing.

This results in a strong demand for improved functionality and performance in display-based applications, such as real-time plotting, smooth animation, and USB camera image capture, in affordable systems. Microprocessors (MPUs) with high-speed, large-capacity built-in memory that can be used like microcontrollers (MCUs) are gaining attention in the market. Renesas' RZ/A3M MPU with a built-in 128MB DDR3L SDRAM and a compatible package for a two-layer PCB design is the ideal solution for realizing smooth animation and high-quality HMI at a reasonable system cost.　　High-Performance HMI and Real-Time Graphics　　Integrating high-speed, large-capacity memory directly into the MPU package offers several advantages, including mitigating concerns about high-speed signal noise on the PCB and simplifying PCB design for the users. The large-capacity memory needed for high-performance HMIs is externally connected to the MPU in the conventional way. Additionally, PCBs equipped with DDR memory and high-speed signal interfaces require multi-layer PCB designs to account for signal noise, making it challenging to reduce PCB costs. Also, the common capacity of on-chip SRAM is typically between 1MB and 10MB, which is too small for high-performance HMIs that need to include a reasonable number of tasks in the near future. To overcome these issues, Renesas released an industry-leading RZ/A3M MPU with a large built-in 128MB DDR3L memory to support high-performance HMI and real-time graphics performance to enhance better and faster user experiences. Most importantly, the board does not require a high-speed signal interface and supports two-layer PCB design to reduce board noise and simplify system development for users.Figure 1. Strengths of Built-in DDR Memory　　Designing High-Performance PCBs at a Reasonable System Cost　　The number of PCB layers and the ease of design significantly impact the cost of system implementation and maintenance in user applications. As shown in Figure 2, using a wide pin pitch of 0.8mm allows for the layout of signal lines and placement of VIAs between the balls. Additionally, placing the balls handling the main signals in the outer rows of the 244-pin 17mm x 17mm LFBGA package and positioning the GND and power pins as inner balls allows for efficient routing of the necessary signal lines for the system (Figure 3). The RZ/A3M MPU is designed to build cost-effective systems with two-layer PCBs through its innovative packaging and pin assignments.Figure 2. Signal Wiring and Ball LayoutImageFigure 3. Optimized Ball Arrangement for a Two-Layer Board Layout　　User-Friendly Interface Enabling Smooth GUI Display　　The high-resolution graphic LCD controller integrated into the RZ/A3M supports both parallel RGB and 4-lane MIPI-DSI interfaces, accommodating displays up to 1280x800. Additionally, the 2D graphics engine, high-speed 16-bit 1.6Gbps DDR3L memory, and 1GHz Arm® Cortex®-A55 CPU enable high-performance GUI displays, including smooth animations and real-time plotting that increase the possibility of automation in HMI applications. Connecting a USB camera to the USB 2.0 interface enables smooth capture of camera images, making it easy to check inside of an apparatus, for example, the doneness of the food in the oven or the condition in the refrigerator.　　The EK-RZ/A3M is an evaluation kit for the RZ/A3M.

　　TAIYO YUDEN CO., LTD. has commercialized four items, including the multilayer metal power inductor MCOIL™ "LACNF2012KKTR24MAB" (2.0 x 1.25 x 1.0 mm, maximum height value shown), which complies with the "AEC-Q200" reliability qualification test standard for passive automotive components. Through advancements made in our proprietary metal materials and multilayer construction methods, we have achieved an upper operating temperature limit of 165°C for a multilayer metal power inductor, a world’s first *1 .　　These products are used as choke coils in DC-DC converters used in automotive engine ECUs, control systems such as BMS, safety systems such as ABS, body-related systems such as ADAS, and information systems such as instrument clusters.　　By extending the upper operating temperature limit range of our conventional product "LCCNF2012KKTR24MAD" (operating temperature range: -55°C to +150°C) to 165°C, these new products are able to contribute to the miniaturization and performance enhancement of power supply circuits by enabling high-density mounting in high-temperature environments such as in automobiles.　　Mass production of these products began at our subsidiary, WAKAYAMATAIYO YUDEN CO., LTD. (Inami-cho, Hidaka-gun, Wakayama Prefecture, Japan), in April 2024. Samples are available for 50 yen per unit.　　The advancements that we have seen in recent years in electronic controls in production vehicles, as typified by ADAS units, has led to a greater number of power supply circuits on vehicles, which in turn has led to growth in the demand for power inductors that are used in these circuits. Furthermore, performance also continues to improve through functional integration, such as in integrated cockpits that combine instrument clusters and infotainment devices. While the throughput of IC chips continues to grow as these devices become increasingly multifunctional and high-performance, there is also a growing need to make on-board electronic components smaller and thinner in order to arrange devices in highly dense configurations and integrate them into single modules. Components mounted at high densities become more susceptible to the effects of heat, as their reduced volumes makes it more difficult for the heat generated by the components to dissipate. Furthermore, since ECUs are increasingly being installed in engine compartments—a high temperature environment—on-board electronic components must be able to withstand high temperatures.　　To address these challenges, TAIYO YUDEN further improved the reliability of the MCOIL™ LCCN series of multilayer metal power inductors, which had the advantage of being smaller and thinner, and launched the AEC-Q200 certified LACN series which provides an extended operating temperature range of - 55°C to +165°C.　　TAIYO YUDEN focuses on the development of products that meet market needs, and will continue to expand its power inductor product lineup.　　*1 As of May 30, 2024, according to TAIYO YUDEN study.　　■Application　　Choke coils in DC-DC converters used in automotive engine ECUs, control systems such as BMS, safety systems such as ABS, body-related systems such as ADAS, and information systems such as instrument clusters.　　■Characteristics　　*2 The saturation current value (Idc1) is the DC current value having inductance decrease down to 30%. (at 20℃)　　*3 The temperature rise current value(Idc2) is the DC current value having temperature increase up to 40℃. (at 20℃)　　*4 The rated current is the DC current value that satisfies both of current value saturation current value and temperature rise current value.　　* Derating of rated current is necessary depending on the ambient temperature.

　　TAIYO YUDEN CO., LTD. has begun mass production of three products, including the LSCND1412FETR47ME (1.4 x 1.2 x 0.65 mm; maximum height shown), in its MCOIL™ LSCN series of multilayer metal power inductors.　　These power inductors are for use as choke coils in the power circuits of smartphones. Retaining the same form factor as our previous product "LSCND1412FETR47MC" (1.4 x 1.2 x 0.65 mm), the DC superposition allowable current of our new "LSCND1412FETR47ME" has been increased by 20% to 3.6 A (previously 3.0 A), and its DC resistance has been reduced by 10% to 38 mΩ (previously 42 mΩ). These improvements contribute to boosting the performance of power supply circuits in smartphones, which are becoming increasingly sophisticated and multifunctional.　　Mass production of these products commenced at our subsidiary WAKAYAMATAIYO YUDEN CO. LTD. (Inami-cho, Hidaka-gun, Wakayama Prefecture, Japan). Samples are available for 50 yen per unit.　　Technology Background　　Smartphones are becoming increasingly sophisticated, with capabilities such as AI-based image and video editing, as well as voice and text translation. At the same time, there is demand for greater efficiency in order to keep their body small, and achieve long operating times with limited battery capacity. To achieve both high performance and high efficiency, a smartphone’s processor operates at high speeds with low voltage and high current, and employs a multi-core configuration where each core is equipped with its own power supply circuit, allowing it to improve both its processing power and efficiency by switching the cores used depending on load. This trend in power supply circuits has become particularly pronounced in cutting-edge smartphones, which require both high performance and high efficiency, and in recent years has led to an increase in the adoption of small and thin low-inductance power inductors capable of handling large currents.　　To address these needs, at TAIYO YUDEN we have been using metallic magnetic materials with high DC superposition characteristics to optimize the design and other aspects of our MCOIL™ LSCN series multilayer metal power inductors—which have the advantage of allowing them to be made more compact and thinner—commercializing three products, including “LSCND1412FETR47ME,” which deliver 20% greater DC superposition allowable current and 10% smaller DC resistance compared to our previous products.　　In response to market needs, we will continue to expand and improve our product lineup with higher functionality and reliability, as well as smaller and thinner products.　　■ Application　　For use as a choke coil for power circuits in smartphones and other devices.　　■Characteristics　　*1 The saturation current value (Idc1) is the DC current value having inductance decrease down to 30%. (at 20℃)　　*2 The temperature rise current value(Idc2) is the DC current value having temperature increase up to 40℃.

These technologies are used in applications such as eye tracking, iris recognition, and blood flow/oxygen saturation measurements that require high accuracy. At the same time, miniaturization, energy efficiency, and design flexibility are becoming increasingly important. In industrial equipment, near-infrared LEDs are playing a greater role with the rise of precise printer control and automation systems. In response, ROHM is expanding customer options by developing a lineup of compact packages and wavelengths that offer greater design flexibility, while contributing to higher precision and power savings by achieving high radiant intensity.　　The new lineup consists of six models in three package configurations, including two ultra-compact (1.0mm × 0.6mm), ultra-thin (t=0.2mm) products as part of the PICOLED™ series: SML-P14RW and SML-P14R3W. In addition, there are four variants in the industry-standard (1.6mm × 0.8mm) size, featuring a narrow beam circular lens package (CSL0902RT, CSL0902R3T) and flat lens design that emits light over a wide range (CSL1002RT, CSL1002R3T). Each package is available in two wavelengths, 850nm (860nm for the SML-P14RW) and 940nm, allowing customers various options for their specific application needs. The 850nm wavelength is ideal for phototransistors and camera sensors, making it suitable for high-sensitivity applications such as eye tracking and object detection in VR/AR. At the same time, the 940nm wavelength is less affected by sunlight and does not appear red when emitting light, making it suitable for motion sensors. It is also widely used in biosensing applications such as pulse oximeters to measure blood flow and oxygen saturation (SpO2).　　The light source incorporates an NIR element with an optimized emission layer structure utilizing proprietary technology developed through in-house manufacturing expertise. This has made it possible to achieve industry-leading* radiant intensity in a compact package, which was previously considered difficult. For example, compared to a standard 1006 size product, the SML-P14RW delivers approx. 1.4 times the radiant intensity at the same current. In other words, the SML-P14RW consumes 30% less power to achieve the same radiation intensity. This technology improves sensing accuracy and power savings for the entire system.　　Going forward, ROHM will continue to provide innovative light source solutions that support next-generation sensing technologies, creating new value in the VR/AR and industrial equipment markets, while contributing to the realization of a sustainable society.　　Compact NIR LED Lineup　　*1:Ta=25°C *2:IF=30mA *3:IF=20mA　　ROHM also offers NIR-sensitive phototransistors.　　Application Examples　　• VR/AR licenses (eye tracking, gesture recognition)　　• Pulse oximeters (blood flow/oxygen saturation measurement)　　• Industrial optical sensors (object passage detection, position detection), self-checkout systems (bill/card detection), mobile printers (paper detection)　　• Home appliance remote controls (IR data communication), robot vacuum cleaners (floor detection)　　Terminology　　VR/AR (Virtual Reality/Augmented Reality)　　Virtual reality immerses users in a completely digital environment through small high-resolution monitors or screens within an enclosed space. Augmented reality enhances the real world by overlaying digital content onto a headset or smart glasses, enabling users to interact with 3D images. Collectively, these technologies are sometimes referred to as XR (Cross Reality or Extended Reality).　　Near-Infrared (NIR)　　Refers to light in the wavelength range of 780nm to 1000nm. Primarily used in sensors, communication and measurement applications, it is suitable for high accuracy distance measurement and recognition.　　PICOLED™ Series　　ROHM's ultra-small, ultra-thin chip LEDs designed for compact mobile devices and wearables, developed using a proprietary element manufacturing process.　　Radiant Intensity　　An index representing the strength of energy emitted by a light-emitting device in a specific direction (unit: W/sr). This is an important factor that affects the LED’s output intensity and detection performance on the receiving side.　　Note: DigiKey™, Mouser™ and Farnell™ are trademarks or registered trademarks of their respective companies.　　*PICOLED™ is a trademark or registered trademark of ROHM Co., Ltd.
