Overview
The NCV7708FDQR2G is a fully protected Hex Half Bridge Driver designed specifically for automotive and industrial motion control applications. This device, produced by onsemi, features six low and high side drivers that are freely configurable and can be controlled separately. This flexibility allows for high side, low side, and H-Bridge control, providing forward, reverse, brake, and high impedance states. The drivers are controlled via a standard SPI interface, making it versatile for various motion control needs.
