NCV7721: Motor Driver, Double Half-Bridge with Direct Control
The NCV7721 is a fully protected Dual Half-Bridge Driver designed specifically for
automotive and industrial motion control applications. The two half-bridge drivers have independent control. This allows for high side, low side, and H-Bridge control. H-Bridge control provides forward, reverse, brake, and high impedance states.
The drivers are controlled via logic level inputs.
