The device provides forward, reverse, and brake modes of operation. A logic supply voltage of 5 V is internally derived from VCC. The TPIC0108B has an extremely low rDS(on), 280 mΩ typical, to minimize system power dissipation. The control inputs (IN1 and IN2) greatly simplify the microcontroller overhead requirement. The device has a low quiescent supply current of 20 µA to suit a wide range of automotive and industrial battery-operated applications. The TPIC0108B provides protection against over-voltage, over-current, over-temperature, and cross conduction faults. Fault diagnostics can be obtained by monitoring the STATUS1 and STATUS2 terminals and the two input control lines. STATUS1 is an open-drain output suitable for wired-or connection. STATUS2 is a push-pull output that prov...
