Data sheet:
Material Declaration:
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 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.
Safe operation of half bridges is ensured by shoot-through diagnosis, dead-time, short to battery, short to ground and open load detection plus a real time phase voltage monitoring.
L9908 is equipped with 3 independent high accuracy current monitor channels with SPI-configurable input differential voltage ranges for ground referenced current measurements, with 5 V/3.3 V output dynamic range compatibility.
L9908 implements diagnostics on external and internal supply, ground level, internal temperature.
A 32-bit out of frame SPI-slave interface is implemented for communication up to 10 MHz between L9908 and uC. SPI communication is safe-guarded by 5-bit CRC, 1bit frame counter, frame length check and an SPI-configurable Window Watchdog.
