The DRV8302DCA is a 3-phase Gate Driver with dual current shunt amplifiers and buck regulator. It provides three half bridge drivers, each capable of driving two N-channel MOSFETs. The device supports up to 1.7A source and 2.3A peak current capability. It can operate off of a single power supply with a wide range from 8 to 60V. It uses a bootstrap gate driver architecture with trickle charge circuitry to support 100% duty cycle. It 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 amplifier support bi-directional current sensing and provide and adjustable output offset up to 3V. The DRV8302 also includes an integrated switching mode buck converter with adjustable output and switching frequency.
