DRV8305 / DRV8305-Q1 Three-Phase Gate Driver

Texas Instruments DRV8305 / DRV8305-Q1 Three-Phase Gate Driver is a gate driver IC for three phase motor drive applications. This device provides three high-accuracy trimmed and temperature compensated half-bridge drivers, each capable of driving a high-side and low-side N-type MOSFET. A charge pump driver supports 100% duty cycle and low voltage operation. The gate driver can also handle load dumps up to 45V. The DRV8305 device includes three bi-directional current shunt amplifiers for accurate low-side current measurements that support variable gain settings and an adjustable offset reference. The device has an integrated voltage regulator (3.3V or 5V) 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 DRV8305-Q1 devices are AEC-Q100 qualified for automotive applications.
