DRV8303DCA

IC, MOTOR DRIV, 3 PHASE, 2.3A, HTSSOP-48.

The DRV8303DCA is a 3-phase Pre-Driver with dual current shunt amplifiers. It provides three half bridge drivers, each capable of driving two N-channel MOSFETs. It 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 6 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 amplifiers support bi-directional current sensing and provide and adjustable output offset up to 3V.
