Description
General part information
DRV8301-Q1 Series
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. VDSof 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.
