DRV8302 具有双路电流感应放大器和降压转换器的三相无刷电机前置驱动器（PWM 控制器）
The 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 2.3A sink and 1.7A source peak current capability and only needs a single power supply with a wide range from 8 to 60V. The DRV8302 uses bootstrap gate drivers with trickle charge circuitry to support 100% duty cycle. The gate driver uses automatic hand shaking when high side FET or low side FET is switching to prevent current shoot through. Vds of FETs is sensed to protect external power stage during overcurrent conditions.
The DRV8302 includes two current shunt amplifiers for accurate current measurement
