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）

Description

The is a gate driver IC for three phase motor drive applications. It provides three half bridge

drivers, each capable of driving two N-channel MOSFETs. The device supports up to 1.7-A source and 2.3-A peak current capability. The DRV8302 can operate off of a single power supply with a wide range from 8-V to 60-V. It uses a bootstrap gate driver architecture with trickle charge circuitry to support 100% duty cycle. The DRV8302 uses automatic hand shaking when the high side or low side MOSFET is switching to prevent current shoot through. Integrated VDS sensing of the high and low side MOSFETs is used to protect the external power stage against overcurrent conditions.
