Description
General part information
STPM801 Series
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.
The STPM801 also monitors the input supply to protect in case of overvoltage (OV) and undervoltage (UV) conditions.
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.
