3 Description
The DRV8303 is a gate driver IC for three-phase
motor-drive applications. The device provides three
half bridge drivers, each capable of driving two N-
channel 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 hand shaking when the high-side or
low-side MOSFET is switching to prevent current
shoot through. Integrated VDS sensing of the high-
side 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 serial peripheral interface (SPI) 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.
