MAX6501, MAX6502, MAX6503, MAX6504 Low-Cost, +2.7V To +5.5V, Micropower Temperature Switches In SOT23 And TO-220

The MAX6501 MAX6502 MAX6503 MAX6504 low-cost, fully integrated temperature switches assert a Logic signal when their die temperature crosses a factory-programmed threshold. Operating from a +2.7V to +5.5V supply, these devices feature two on-chip, temperature-dependent voltage references and a Comparator They are available with factory-trimmed temperature trip thresholds from -45C to +125C in 10C increments, and are accurate to 0.5C (typ) 739 or 6C (max). These devices require no external components and typically consume 30A supply current. Hysteresis is pin-selectable at +2C or +10C.
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 +125C), 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 MAX6501 MAX6504 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.
