📥 Download Datasheet

General Description

The DRV8305 device is a gate driver IC for threephase motor-drive applications.

The device provides three high-accuracy and temperature compensated 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.
