Texas Instruments DRV8302 Three Phase Pre-Driver

Texas Instruments DRV8302 Three-Phase Pre-Driver is a gate driver IC for three-phase motor drive applications. The DRV8302 Three-Phase Pre-Driver provides three half-bridge drivers, each capable of driving two N-type MOSFETs, one for the high side and one for the low side. This device supports up to 2.3A sink and 1.7A source peak current capability and needs only a single power with a wide range from 8 to 60V.

The Texas Instruments DRV8302 uses bootstrap gate drivers with trickle charge circuitry to support a 100% duty cycle. The DRV8302 gate driver includes two current shunt amplifiers for accurate current measurement. This gate driver also has an integrated switching mode buck converter with adjustable output and switching frequency to support MCU or additional system power needs.
