The is a Gate Driver Integrated Circuit for three-phase motor drive applications. The device provides three half-bridge drivers, each capable of driving two N-channel MOSFETs. The DRV8301 supports up to 1.7A source and 2.3A peak current capability. The IC can operate off of a single power supply with a wide range from 6V to 60V. The device uses bootstrap gate driver architecture with trickle charge circuitry to support 100% duty cycle. The IC uses automatic handshaking when the high-side or low-side MOSFET is switching to prevent flow of current. Integrated VDS sensing of the high-side and low-side MOSFETs is used to protect the external power stage against over-current conditions. This IC includes two current shunt amplifiers for accurate current measurement and also includes an integrated switching mode buck converter with adjustable output and switching frequency. The amplifiers support bidirectional current sensing and provide an adjustable output offset up to 3V.
