The Maxim Integrated MAX6501UKP125 is a micropower temperature switch that pulls its output low when the die temperature crosses a factory-set trip point.
No last-time-buy clock ticking, no forced redesign to a second source. For legacy designs or military/aerospace builds where leaded finish is preferred, this is exactly the part you want.
Sourcing this part for your BOM
Because the MAX6501UKP125 is active and RoHS non-compliant, it is not a part every distributor stocks in depth. If you are filling a prototype run or a production line, send the RFQ — we will come back with a firm price and lead time, not a maybe.
