The MAX6501/MAX6503 have an active-low, open-drain output intended to interface with a microprocessor (P) reset input. The MAX6502/MAX6504 have an activehigh, push-pull output intended to directly drive fancontrol logic. The MAX6501/MAX6502 are offered with hot-temperature thresholds (+35C to +115C), asserting when the temperature is above the threshold. The MAX6503/MAX6504 are offered with cold-temperature thresholds (-45C to +15C), asserting when the temperature is below the threshold. The MAX6501MAX6504 are offered in eight standard temperature versions; contact the factory for pricing and availability of nonstandard temperature versions. They are available in 5-pin SOT23 and 7-pin TO-220 packages.
