Part Number : DRV8301
Function : Automotive 3-Phase BLDC Pre-Driver w/ Dual Current Sense Amps and Buck Converter
Manufacturers : Texas Instruments
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.
