On the auto-retry version (STELPD01A), the EN/Fault pin is pulled down and the device attempts to turn on

output channel with soft-start ramp after a delay time of 100 µs.

is turned off and the load is disconnected.

On the latched version (STELPD01), the EN/Fault pin of the device is automatically set to the intermediate

The device can be reset from this condition either by cycling the supply voltage or by pulling down the EN pin

On the auto-retry version (STELPD01A), the EN/Fault pin is set low, and the auto-retry circuit attempts to restart

the device with soft-start ramp once the die temperature is reduced to 145 °C typ. (165 °C minus the hysteresis

value, 20 °C typ.).

EN/Fault pin

The EN/Fault pin has the dual function of controlling the output of the device and providing information about the

device status to the application.

When it is used as a standard Enable pin, it can be connected to an external open-drain or open-collector device.

In this case, when it is pulled at low logic level, the device turns the output off, when it is left floating the device

turns on the output, since it has internal pull-up circuitry.

provided to a monitor circuit, informing it that a fault event has occurred or it can be directly connected to the

EN/Fault pins of other devices of the same family on the same application in order to achieve a simultaneous

order to keep the device in off-state.
