Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The DRV3245BQPHPRQ1 is a FET gate driver IC for three-phase motor drive applications and is designed to meet the requirements of ISO 26262 for functional safety applications. The device features three half-bridge drivers, each capable of driving both high-side and low-side N-channel MOSFETs, along with advanced FET protection and monitoring. The charge pump drivers achieve 100% duty cycle during cold start operation and support low battery voltages. With integrated current-sense amplifiers, phase comparators, and SPI-based configuration and peripherals, the drivers eliminate most external and passive components, reducing bill of materials and printed circuit board (PCB) space.
