3 Description

The DRV8303 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 device supports up to 1.7-A

source and 2.3-A peak current capability. The

DRV8303 can operate off of a single power supply

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

bootstrap gate-driver architecture with trickle charge

circuitry to support 100% duty cycle. The DRV8303

uses automatic hand shaking when the high-side or

low-side MOSFET is switching to prevent current

shoot through. Integrated VDS sensing of the highside

and low-side MOSFETs is used to protect the

external power stage against overcurrent conditions.

The DRV8303 includes two current-shunt amplifiers

for accurate current measurement. The amplifiers

support bi-directional current sensing and provide and

adjustable output offset up to 3 V.

The serial peripheral interface (SPI) provides detailed

fault reporting and flexible parameter settings such as

gain options for the current-shunt amplifiers and slewrate

control of the gate drivers.
