3 Description

The DRV8305 device is a gate driver IC for threephase

motor-drive applications. The device provides

three high-accuracy and temperature compensated

half-bridge drivers, each capable of driving a highside

and low-side N-channel MOSFET. A charge

pump driver supports 100% duty cycle and lowvoltage

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.
