NCV7708
Double Hex Driver
The NCV7708 is a fully protected Hex−Half Bridge−Driver
designed specifically for automotive and industrial motion control
applications. The six low and high side drivers are freely configurable
and can be controlled separately. 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 a
standard SPI interface.
