DRV8305 Overview
The DRV8305 device is a gate driver IC for threephase motor-drive applications. The device provides three high-accuracy and temperature pensated half-bridge drivers, each capable of driving a highside and low-side N-channel MOSFET. A charge pump driver supports 100% duty cycle and lowvoltage operation.
