Note 1: Fault output level is referenced Low when over current or under voltage for Vcc is detected.

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.

Note 1. Over-current detection level is determined by the following equation

Ioc=Voc/Rs

Note.2 This IC has filters of 0.4us for noise reduction.

But appropriate R1, C1 should be added when noise can not be removed.
