  • Hi Kuo John,

    If the output is high and shorted to GND, this would be considered an overcurrent (OCP) event. The device should protect itself by disabling the outputs as described in section 9.3.10 of the datasheet.

    Would you provide a diagram of the test performed?
    What were the input states?
    How was OUT+ shorted to GND?
    What type of damage occurred?
