Overview
The NCV7707DQBR2G, produced by onsemi, is a powerful Driver-IC designed specifically for automotive body control systems. This monolithic IC is engineered to control various loads in the front door of a vehicle, including mirror functions such as positioning, heating, and folding, as well as electro-chromatic mirror features. The device also controls lock and safe-lock motors through two half-bridge outputs and drives LEDs or incandescent bulbs up to 10 W via four high-side outputs. The NCV7707DQBR2G offers maximum flexibility with PWM control through external signals or an internal programmable PWM generator unit, all managed via a 24-bit SPI interface.
