Note 2: Over current protection works when the voltage drop of the external sensing resistor exceeds the threshold voltage Voc(typical 0.49V). In this case all six outputs are turned off and Fault output level becomes low. Reset after detection is done by feeding high signal to all six inputs or re-supplying Vcc voltage. Note 3: The output signal for Fault is reset by feeding high signal to all six inputs. 5.
