DRV8303 Three-Phase Pre-Driver

TI's gate-driver IC for three-phase motor-drive applications

Image of Texas Instruments' DRV8303 Three-Phase Pre-Driver Texas Instruments' DRV8303 is a gate-driver IC for three-phase motor-drive applications. It provides three half-bridge drivers, each capable of driving two N-type MOSFETs, one for the high-side and one for the low-side. It supports up to 2.3 A sink and 1.7 A source peak current capability and only needs a single power supply with a wide range from 6 to 60 V. The DRV8303 uses bootstrap gate drivers with trickle-charge circuitry to support 100% duty cycle. The gate driver uses automatic hand shaking when high- or low-side FET is switching to prevent current shoot-through. VDS of FETs is sensed to protect external power stage during overcurrent conditions.

The DRV8303 includes two current shunt amplifiers for accurate current measurement. The current amplifiers support bi-directional current sensing and provide an adjustable output offset of up to 3 V. The SPI interface provides detailed fault reporting and flexible parameter settings such as gain options for current shunt amplifier and slew-rate control of gate driver.
