MAXIM MAX6501UKP045+T

The MAX6501 - 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 - 45°C to +125°C in 10°C increments, and are accurate to ±0.5°C (typ) or ±6°C (max). These devices require no external components and typically consume 30μA supply current. Hysteresis is pin - selectable at 2°C or 10°C. The MAX6501/MAX6503 have an active - low, open - drain output 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 with hot - temperature thresholds (+35°C to +125°C) asserting when the temperature is above the threshold. The MAX6503/MAX6504 are offered with cold - temperature thresholds (- 45°C to +15°C) 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 a 5 - pin SOT23 package.
