L9908 - STMicroelectronics

L9908 Automotive 3-Phase motor gate driver

L9908 is a gate driver unit (GDU) for controlling 6 N-channel FETs for brushless motors in automotive applications. Each one of the 3 half bridge drivers channels (HS/LS couples) can be independently configured allowing different load driving and is able to withstand -14 V to 95 V excursion on motor`s pins. Through 6 dedicated parallel inputs the pre-driver .
