DRV8302 Three-Phase Pre-Driver

Texas Instruments' three phase pre-driver with dual current shunt amplifiers and buck regulator

DRV8302 Three Phase Pre-DriverTexas Instruments' DRV8302 is a gate driver IC for three phase motor drive applications. It provides three half bridge drivers, each capable of driving two N-type MOSFETs, one for the high-side and one for the low side. It supports up to 2.3 A sink and 1.7 A source peak current capability, has a wide supply input range from 8 to 60 V and only needs a single power supply. The DRV8302 uses bootstrap gate drivers with trickle charge circuitry to support 100% duty cycle. The gate driver uses automatic hand shaking when the high or low side FET is switching to prevent current shoot through. Vds of the FETs is sensed to protect external power stage during overcurrent conditions.
