3 Description
The DRV8303 is a gate driver IC for three phase
motor drive applications. It provides three half bridge
drivers, each capable of driving two N-channel
MOSFETs. It 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 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 3 V.
The SPI interface provides detailed fault reporting
and flexible parameter settings such as gain options
for the current shunt amplifiers and slew rate control
of the gate drivers.
