Adicionar à lista técnicaL9908TR Descrição geral
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.Specific CAN-controlled brushless motor evaluati.Specific CAN-controlled brushless motor evaluati.
