The DRV8305 device is a gate driver IC for three-phase motor-drive applications. The device provides three high-accuracy and temperature compensated half-bridge drivers, each capable of driving a high-side and low-side N-channel MOSFET. A charge pump driver supports 100% duty cycle and low-voltage operation. The device can tolerate load dump voltages up to 45-V.

The DRV8305 device includes three bidirectional current-shunt amplifiers for accurate low-side current measurements that support variable gain settings and an adjustable offset reference.

The DRV8305 device has an integrated voltage regulator (3.3-V or 5-V) to support an MCU or other system power requirements. The voltage regulator can be interfaced directly with a standard LIN physical interface to allow low system standby and sleep currents.

The gate driver uses automatic handshaking when switching to prevent current shoot through. The VDS of both the high-side and low-side MOSFETs is accurately sensed to protect the external MOSFETs from overcurrent conditions. The SPI provides detailed fault reporting, diagnostics, and device configurations such as gain options for the current shunt amplifier, individual MOSFET overcurrent detection, and gate-drive slew-rate control.
