Overview

STPM801 Datasheet Automotive high voltage hot swap, soft start and oring Features VFQFN-32 (5x5 mm) Product status link STPM801 Product summary Order code Package Packing STPM801 VFQFN-32 STPM801-TR Tray Tape and Reel • AEC-Q100 qualified • Single channel • Wide input voltage range: 4 V to 65 V • Reverse input protection -65 V • 2 external N-channel MOSFET pre-drivers – One soft start feature – One oring feature • Quiescent current < 50 μA if WAKE low • Integrated charge pump • Input overvoltage protection • Input undervoltage protection • Output overcurrent protection • Complies with the 16750 AC ripple test requirements (50 Hz - 25 kHz) • Adjustable soft start with external capacitor • Developed according to ISO 26262 to support ASIL D application 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.
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.
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.
