Product Details
MAX4925ELT+T - Overvoltage Protection Controller for External pFET
MAX4925ELT+T from Analog Devices Inc. / Maxim Integrated is a low-current overvoltage protection controller that drives an external p-channel MOSFET and withstands input faults up to 28 V.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
MAX4925 monitors the input supply and disconnects a protected load through an external p-channel MOSFET when an overvoltage condition exceeds its fixed threshold.
Key Advantages
Protects low-voltage circuitry from input faults as high as 28 V using a properly rated external pFET.
Uses only 13 uA typical supply current and adds startup debounce plus a fault flag.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
External-pFET overvoltage protection controller
Analog input monitor, pFET gate-drive output and active fault flag
Up to 28 V fault input; 5.65 V typical OVLO; 2.44 V UVLO; -40 C to +85 C
6-WFDFN
Package & Footprint
This ordering code uses the 6-WFDFN package.
Pin Functions
Confirm exact numbering and the latest land pattern before PCB release.

Manufacturer Information
Analog Devices product documentation was checked for the MAX4925 and the ELT+T order code.
Applications
Isolates a low-voltage rail when a charger or adapter applies excessive voltage.
Adds compact front-end protection before downstream power-management circuitry.
Quality & Authenticity
Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.
