PWM output temperature sensor — what it is and where it fits
The MAX6672AXK-T from Maxim Integrated is a PWM output temperature sensor. It delivers a digital pulse-width modulated signal proportional to the measured temperature, which a microcontroller or timer input can decode directly without an ADC. This makes it a clean fit for designs where an analog voltage output would pick up noise over a long trace or where the host already has a capture-timer input available.
RoHS status — check your BOM compliance
This part is marked RoHS non-compliant. If your assembly process or end-market requires RoHS (e.g. EU RoHS, China RoHS, or a corporate environmental policy), the MAX6672AXK-T will not pass the material declaration. Plan for a leaded-solder process or evaluate a RoHS-compliant alternative in the same function family.
Lifecycle and sourcing reality
For a BOM line that needs this exact PWM temperature sensor, the supply chain is stable — no urgency to stockpile or qualify a substitute.
