MAX6501UKP115 ________________General Description

The MAX6501–MAX6504 low-cost, fully integrated tem-perature switches assert a logic signal when their dietemperature crosses a factory-programmed threshold.Operating from a +2.7V to +5.5V supply, these devicesfeature two on-chip, temperature-dependent voltagereferences and a comparator. They are available withfactory-trimmed temperature trip thresholds from -45°Cto +125°C in 10°C increments, and are accurate to±0.5°C (typ) or ±6°C (max). These devices require noexternal components and typically consume 30µA sup-ply current. Hysteresis is pin-selectable at 2°C or 10°C.The MAX6501/MAX6503 have an active-low, open-drainoutput intended to interface with a microprocessor (µP)reset input. The MAX6502/MAX6504 have an active-high, push-pull output intended to directly drive fan-control logic. The MAX6501/MAX6502 are offered withhot-temperature thresholds (+35°C to +125°C), assert-ing when the temperature is above the threshold. TheMAX6503/MAX6504 are offered with cold-temperaturethresholds (-45°C to +15°C), asserting when the tem-perature is below the threshold.The MAX6501–MAX6504 are offered in eight standardtemperature versions; contact the factory for pricingand availability of nonstandard temperature versions.They are available in a 5-pin SOT23 package.
