NCV7703 Datasheet, PDF (1/16 Pages) ON Semiconductor – Triple Half-Bridge Driver with SPI Control

NCV7703
Triple Half-Bridge Driver
with SPI Control
The NCV7703 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 SPI (Serial Peripheral
Interface). This device is fully compatible with ON Semiconductor’s
NCV7708 Double Hex Driver.
