Product details

Micropower temperature switch — what it does

The Maxim MAX6504UKN045 is a micropower temperature switch that asserts a digital output when the local die temperature crosses a factory-programmed threshold. It is designed for overtemperature detection in battery-powered or thermally constrained systems where continuous monitoring is required without the overhead of an ADC or software polling.

RoHS non-compliance — plan for it

This part is RoHS non-compliant, meaning the solder terminations contain lead. It is suitable for military, aerospace, or industrial builds that are exempt from RoHS restrictions.

Because it is a single-sourced Maxim part, dual-sourcing is not an option — plan for sole-source risk by stocking a reasonable buffer if the BOM line is critical.

Frequently asked questions

What is the function of MAX6504UKN045?

It is a micropower temperature switch that outputs a digital signal when the local temperature exceeds a factory-set threshold. It is used for overtemperature alarm or shutdown in battery-operated equipment, power supplies, and thermal management circuits.

Is MAX6504UKN045 RoHS compliant?

No, this part is RoHS non-compliant. It uses lead-bearing solder terminations and is intended for applications that allow lead under exemption.

What are alternatives or equivalents to MAX6504UKN045?

Maxim offers other micropower temperature switches in the same family with different threshold temperatures. For a RoHS-compliant equivalent, a lead-free variant from the same series should be selected. No pin-compatible second source from another manufacturer is listed on the record.
