DESCRIPTION
The DRV8301-Q1 is an automotive gate driver IC for
three phase motor drive applications. It provides three
half bridge drivers, each capable of driving two
N-type MOSFETs, one for the high-side and one for
the low side. It supports up to 2.3A sink and 1.7A
source peak current capability and only needs a
single power supply with a wide range from 6V to
60V. The DRV8301-Q1 uses bootstrap gate drivers
with trickle charge circuitry to support 100% duty
cycle. The gate driver uses automatic hand shaking
when high side FET or low side FET is switching to
prevent current shoot through. Vds of FETs is sensed
to protect external power stage during overcurrent
conditions.
The DRV8301-Q1 includes two current shunt
amplifiers for accurate current measurement. The
current amplifiers support bi-directional current
sensing and provide an adjustable output offset of up
to 3V.
The DRV8301-Q1 also has an integrated switching
mode buck converter with adjustable output and
switching frequency to support MCU or additional
system power needs. The buck is capable to drive up
to 1.5A load.
The SPI interface provides detailed fault reporting
and flexible parameter settings such as gain options
for current shunt amplifier, slew rate control of gate
driver, etc.
