The DRV3245E-Q1 device is a FET gate driver IC for three-phase motor-drive applications. The device is intended for high-temperature automotive applications and is 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 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.

The DRV3245E-Q1 device also integrates diagnostics and protection for each internal block and provides support for common system diagnostic checks each of which can be instantiated and reported through SPI. This flexibility of the integrated features allows the device to integrate seamlessly into a variety of safety architectures.
