3 Description
The DRV8301 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 DRV8301 supports up to
1.7-A source and 2.3-A peak current capability. The
DRV8301 can operate off of a single power supply
with a wide range from 6-V to 60-V. The device uses
a bootstrap gate driver architecture with trickle charge
circuitry to support 100% duty cycle. The DRV8301
uses automatic handshaking when the high-side or
low-side MOSFET is switching to prevent flow of
current. Integrated VDS sensing of the high-side and
low-side MOSFETs is used to protect the external
power stage against overcurrent conditions.
The DRV8301 includes two current shunt amplifiers
for accurate current measurement. The amplifiers
support bidirectional current sensing and provide an
adjustable output offset up to 3 V.
The DRV8301 also includes an integrated switching
mode buck converter with adjustable output and
switching frequency. The buck converter can provide
up to 1.5 A to support MCU or additional system
power needs.
The 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.
