DRV594VFPR

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 chargepump 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.
