Hex Half-Bridge Driver

NCV7723B

The NCV7723B is a six channel half−bridge driver with protection features designed specifically for automotive and industrial motion control applications. The product has independent controls and diagnostics, and the drivers can be operated in forward, reverse, brake, and high impedance states. The device is controlled via a 16 bit SPI interface and is daisy chain compatible. Outputs 1 and 2 can be controlled through an external PWM signal.
