NCV7703B
Triple Half-Bridge Driver
with SPI Control
The NCV7703B is a fully protected Triple Half−Bridge Driver
designed specifically for automotive and industrial motion control
applications. The three 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 a standard Serial Peripheral Interface
(SPI). This device is fully compatible with ON Semiconductors
NCV7708 Double Hex Driver.
