Product details

What this overvoltage-protection IC does

The Maxim MAX4945LELA+ is an overvoltage-protection IC designed to clamp or disconnect downstream circuitry when the input supply exceeds a safe threshold. It is used in power-management chains where a single fault on the input rail could damage sensitive loads — think portable instruments, base-station line cards, or automotive infotainment modules that share a bus with higher-voltage supplies.

If your pick-and-place line expects reeled parts, factor in a tube-to-reel transfer or hand-place for prototype runs.

Frequently asked questions

Is the MAX4945LELA+ still active or is it obsolete?

The MAX4945LELA+ is listed as Active in production. No discontinuation notice has been issued for this order code.

What is the MAX4945LELA+ used for?

It is an overvoltage-protection IC that protects downstream circuitry from supply-rail faults. Typical applications include power-management front-ends in industrial, telecom, and automotive equipment where a single overvoltage event could damage converters or loads.

Is MAX4945LELA+ RoHS compliant?

Yes, the MAX4945LELA+ is RoHS compliant. The part carries the '+' suffix which indicates lead-free and RoHS-compliant finish from Maxim.
