The device provides three half bridge drivers, each capable of driving two Nchannel MOSFETs. The device 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...
