NCV7703B: Motor Driver, Triple, Half-Bridge, 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 SPI (Serial Peripheral Interface). This device is fully compatible with ON Semiconductor's NCV7708B Double Hex Driver.
