STMicroelectronics L9908TR, BLDC Motor Driver IC

The STMicroelectronics Automotive 3-Phase motor gate driver unit 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 stages can be controlled independently supporting duty cycle operations from 0% to 100% and allowing to implement all kinds of electric motor control strategy. A dedicated combination of regulators, charge pumps and bootstrap circuits allows L9908 to be suitable to operate in passenger, commercial or hybrid vehicles.
