NCV7718B
Hex Half-Bridge Driver
The NCV7718B is a Hex Half−Bridge Driver with protection
features designed specifically for automotive and industrial motion
control applications. The NCV7718B has independent controls and
diagnostics. The device can be operated in forward, reverse, brake,
and high impedance states. The drivers are controlled via a 16 bit SPI
interface and are daisy chain compatible.
