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
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.
