DRV8305NQPHPRQ1 Description
The DRV8305-Q1 device is a gate driver IC for threephase 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 lowsystem standby and sleep currents. DRV8305NQPHPRQ1
