3 Description
The DRV8301-Q1 device is an automotive gate driver
IC for three phase motor drive applications. The
device provides three half bridge drivers, each
capable of driving two N-type MOSFETs, one for the
high-side and one for the low side. The device
supports up to 2.3-A sink and 1.7-A source peak
current capability and only needs a single power
supply with a wide range from 6 to 60 V. The
DRV8301-Q1 device 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 device 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 3 V.
The DRV8301-Q1 device 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 1.5-A 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, and other settings.
