Overview
The NCV7703C, specifically the NCV7703CD2R2G, is a fully protected Triple Half-Bridge Driver designed by onsemi for automotive and industrial motion control applications. This device features three independent half-bridge drivers, each capable of high side, low side, and H-Bridge control. The drivers are controlled via a standard Serial Peripheral Interface (SPI), enabling precise and efficient control over motor management and other motion control tasks.
