4-Channel BTL Driver
* Wide dynamic range, (4.0V (typ.) at PreVcc=12V, PVcc=5V,
RL=8Ω)
* Level shift circuit built in.
* Thermal-shut-down circuit built in.
* UTC UA8954 is a 4 channel driver for optical disc motor driver.
Dual channel current feedback type drivers are built in, in addition to dual
channel motor drivers.
* Stand-by mode built in.
* Separating Vcc into Pre+Power of sled motor, Power of loading
motor and Power of actuator, can make better power efficiency,
by low supply voltage drive.
Current phase lag influenced load inductance is little, because
this type is current feedback.
Input pins consist of (+) and (-), therefore various input types are
available such as differential input.
This is a single input Iinear BTL driver. |
