DRV8301 Three Phase Pre-Driver

Texas Instruments DRV8301 Three Phase Pre-Driver with dual current shunt amplifiers and buck regulator is a gate driver IC for three-phase motor drive applications. The TI DRV8301 provides three half-bridge drivers, each capable of driving tow N-type MOSFETs - one for the high side and one for the low side. This three-phase pre-driver 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 8 to 60V. The TI DRV8301 uses bootstrap gate drivers with trickle charge circuitry to support a 100% duty cycle. This TI gate driver IC 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 Texas Instruments DRV8301 also has an integrated switching mode buck converter with adjustable output and switching frequency to support MCU or additional system power needs.
