The DRV8305-Q1 device is a gate driver IC for three-phase motor-drive applications. The device provides three high-accuracy 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 for cold crank situations. The device can tolerate load dump voltages up to 45-V.

The DRV8305-Q1 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-Q1 device has an integrated voltage regulator to support an MCU or other system power requirements. The voltage regulator can be interfaced directly with a 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.

Device Options:

  • DRV8305NQ: Grade 1 with voltage reference
  • DRV83053Q: Grade 1 with 3.3-V, 50-mA LDO
  • DRV83055Q: Grade 1 with 5-V, 50-mA LDO
  • DRV8305NE: Grade 0 with voltage reference
