Texas Instruments DRV3245E-Q1 3-phase Automotive Gate Driver Unit

Texas Instruments DRV3245E-Q1 3-phase Automotive Gate Driver Unit (GDU) offers high-performance current sensing for three-phase motor-drive applications. The DRV3245E-Q1 is intended for high-temperature automotive applications and is designed according to the applicable requirements of ISO 26262 for functional safety applications. The device features three half-bridge drivers, each capable of driving a high-side and low-side N-channel MOSFET, concurrently providing enhanced FET protection and monitoring.

The DRV3245E-Q1 has a charge-pump driver providing 100% duty cycle and supports low battery voltages during cold-crank operation. The device offers a reduction of the bill of materials (BOM) and space on the printed circuit board (PCB) with the integration of current-sense amplifiers, integrated phase comparators, and SPI-based configuration. The Texas Instruments DRV3245E-Q1 devices are AEC-Q100 qualified for automotive applications.
