3 Description

The DRV8301 is a gate driver IC for three-phase

motor drive applications. The device provides three

half-bridge drivers, each capable of driving two Nchannel

MOSFETs. The DRV8301 supports up to

1.7-A source and 2.3-A peak current capability. The

DRV8301 can operate off of a single power supply

with a wide range from 6-V to 60-V. The device uses

a bootstrap gate driver architecture with trickle charge

circuitry to support 100% duty cycle. The DRV8301

uses automatic handshaking when the high-side or

low-side MOSFET is switching to prevent flow of

current. Integrated VDS sensing of the high-side and

low-side MOSFETs is used to protect the external

power stage against overcurrent conditions.

The DRV8301 includes two current shunt amplifiers

for accurate current measurement. The amplifiers

support bidirectional current sensing and provide an

adjustable output offset up to 3 V.

The DRV8301 also includes an integrated switching

mode buck converter with adjustable output and

switching frequency. The buck converter can provide

up to 1.5 A to support MCU or additional system

power needs.

The SPI provides detailed fault reporting and flexible

parameter settings such as gain options for the

current shunt amplifiers and slew rate control of the

gate drivers.
