Does anyone know what the output capability is of the FAULTZ pin ? I mean ,can it drive a LED direct as the datasheet does not seem to say anywhere ?

    Hi Chris,

    Faultz is designed to handle 5mA maximum average current. But you will not be able to configure it auto-recovery by connecting FAULTz to SDz if you sink that much current into FAULTz. The internal resistance seen at FAULTz is about 135 Ohms (which can vary due to PVT) and the VIH of SDz is 0.8V.
