NOVOSENSE Launches Next-Generation Isolated CAN Transceiver NSI1150, Supporting ±70V Bus Fault Protection and Higher Data Rates

　　NOVOSENSE today announced the launch of its new industrial-grade isolated CAN transceiver, the NSI1150 series. Built on NOVOSENSE's third-generation isolation technology, the device delivers ±70V bus fault protection and up to ±150kV/μs (typical) common-mode transient immunity (CMTI). Compared to the previous generation (NSI1050), the NSI1150 achieves a comprehensive improvement in reliability and noise immunity. It also integrates NOVOSENSE's proprietary CAN FD transceiver, supporting communication speeds of up to 5 Mbps.

　　The NSI1150 is available in multiple package options, including SOW16, SOW8, SOP8, SOWW8, and DUB8, addressing diverse design requirements. It is well suited for high-voltage, high-noise, multi-node applications such as industrial automation and control, energy and power systems, as well as communications and servers.

　　Reliability Upgrade for Harsh Environments

　　The NSI1150 delivers industry-leading reliability and robustness, featuring a high CMTI of ±150kV/μs (typical) and ±70V bus fault protection, enabling it to effectively handle strong electromagnetic interference and ground potential differences in demanding environments.

　　In addition, all pins support ±6kV HBM ESD protection and 10kV surge capability across the isolation barrier, ensuring stable communication even under extreme conditions. The device offers multiple isolation ratings—3 kVRMS, 5 kVRMS, and 7.5 kVRMS—to meet stringent safety requirements across various applications, reinforcing system protection in critical sectors such as industrial automation and energy infrastructure.

　　Multiple Package Options for Flexible Design

　　The NSI1150 is offered in five mainstream package options—SOW16, SOW8, SOP8, SOWW8, and DUB8—accommodating different space constraints and safety requirements. Among them, the newly introduced SOWW8 wide-body package provides up to 15 mm creepage distance, making it ideal for applications with strict creepage requirements, such as photovoltaic systems, EV charging stations, and industrial power supplies.

　　This extended creepage distance simplifies safety certification processes and enables more flexible layout design for high power density systems. The diversified package portfolio further enhances design flexibility and accelerates time-to-market.
