What this part is and where it fits
The Maxim Integrated MAX6502UKP055 is a micropower temperature switch designed to assert a digital output when the die temperature crosses a factory-programmed threshold. It is used for over-temperature protection, fan control, and thermal monitoring in battery-powered or thermally constrained equipment where low quiescent current matters.
RoHS status — a design constraint
This part is RoHS non-compliant, meaning it contains lead or other restricted substances above the exemption thresholds. For designs that must meet RoHS requirements (e.g., CE-marked consumer goods sold in the EU after the RoHS directive effective dates), this part is not a fit. It is suited for legacy BOMs, military/aerospace applications with leaded-solder exemptions, or repair stock where RoHS compliance is not mandated.
Sourcing and availability
