DRV3245Q-Q1 Gate Driver Unit (GDU)

Texas Instruments DRV3245Q-Q1 Gate Driver Unit (GDU) is a FET gate driver IC for three-phase motor-drive applications designed according to the applicable requirements of ISO 26262 for functional safety applications. The device provides three half-bridge drivers each capable of driving a high-side and low-side N-channel MOSFET while also providing sophisticated protection and monitoring of the FETs. A charge-pump driver enables 100% duty cycle and supports low battery voltages during cold-crank operation. The integration of current-sense amplifiers, integrated phase comparators, and SPI-based configuration of the driver and its peripherals enable reduction of the bill of materials (BOM) and space on the printed circuit board (PCB) because of the elimination of most external and passive components.
