The DRV8303 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. It 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 high 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 SPI interface 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.
