DRV8301 - Pre-driver for 3-Phase Dual Current Shunt Amplifier and Buck Regulator

DRV8301 - 3-Phase Dual Current Shunt Amplifier and Pre-Driver for Buck Regulators
The DRV8301 is a three-phase gate driver IC for motor drive applications. It provides 3 half-bridge drivers, each capable of driving two N-type high-side and low-side MOSFETs, square. It supports up to 2.3A sink and 1.7A source peak current capability, requiring only one power supply to supply a wide range of 8 to 60V. The DRV8301 uses a drop-in boot gate driver charging circuit that supports 100% duty cycle. Gate drivers use automatic handshaking when high-side FET or low-side FET switches to prevent current shoot through. The VDS detects the FET protection stage during overcurrent conditions of the external power supply. The DRV8301 includes two current shunt amplifiers for accurate current measurement. The current amplifier supports bidirectional current sensing and provides an adjustable output offset of 3V.
The DRV8301 also features an adjustable output integrated switch-mode buck converter and switches to support the frequency needs of an MCU or other system power supply. The buck is capable of driving loads up to 1.5A. SPI interface provides detailed fault reporting Flexible parameter settings such as gain options, current shunt amplifiers, slew rate control gate drivers, etc.
