Description

STPM801 offers integrated hot swap, soft start and oring protections. It protects

loads from high voltage transients, limiting and regulating the output during an

overvoltage event, such as load dump, by controlling the voltage drop across an

external N-channel MOSFET.

Product summary

The STPM801 also monitors the input supply to protect in case of overvoltage (OV)

and undervoltage (UV) conditions.

Package

Packing

STPM801

Tray

An integrated ideal diode controller drives a second MOSFET (the oring) to replace a

Schottky diode for reverse input protection and output voltage holdup. The STPM801

controls the forward voltage drop across the MOSFET and minimizes reverse current

transients in case of fault like power source failure, brownout or input short.

STPM801 offers a set of features to support applications that need to fulfill functional

safety requirements as defined by automotive Safety Integrity Level (ASIL) A-B-C-D

depending on application TSR.
