Product Details
MAX6495ATT/V+ - Automotive 72 V Overvoltage Protection Controller
MAX6495ATT/V+ from Analog Devices Inc. / Maxim Integrated is an AEC-Q100 qualified 5.5 V to 72 V overvoltage switch and limiter controller for an external n-channel MOSFET.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
MAX6495 monitors a resistor-programmed overvoltage threshold and controls an external n-channel MOSFET. The circuit can disconnect a load during an overvoltage event or regulate the MOSFET in limiter mode while providing fast gate discharge and thermal protection.
Key Advantages
A 5.5 V to 72 V input range, AEC-Q100 qualification and -40 C to +125 C operation suit automotive load-dump and industrial supply protection.
The internal charge pump enhances the external nMOSFET gate about 10 V above the monitored node, while a 100 mA pulldown provides rapid turn-off during faults or shutdown.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
Automotive high-voltage overvoltage switch and limiter controller
Analog OVSET divider, active-low shutdown, external nMOSFET GATE drive and OUTFB sensing
5.5 V to 72 V supply; adjustable overvoltage threshold; -40 C to +125 C
6-WDFN Exposed Pad

Replacement Considerations
MAX6495ATT/V+T is a related product in the library. Confirm electrical behavior, package, pinout, ordering media and configuration before substitution.
Similarity of family name or package does not establish drop-in compatibility.
Manufacturer Information
Analog Devices' production product page and Rev. 18 data sheet were checked for the exact AEC-Q100 tube-packed order code.
Applications
Protects downstream ECUs and converters from high-voltage battery-line transients using an appropriately rated external MOSFET.
Implements an adjustable disconnect or voltage-limiting front end for wide-input power systems.
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.
FAQ
