The STELPD01 is an integrated electronic power switch for power rail protection applications.


It is able to precisely detect and react to overcurrent and overvoltage conditions.


When an overload condition occurs, the device goes into an open state, disconnecting the load from the power supply. An external power MOSFET can be driven to manage the power loss protection in case of fault condition.


In case of overvoltage on the input, the device regulates the output to a preset 17.5 V value.


Undervoltage lockout prevents the load from malfunction, keeping the device off if the rail voltage is too low.


The STELPD01 features an adjustable turn-on slew-rate, which is useful to keep the in-rush current under control during startup and hot-swap operations.
