Overview
19-1280; Rev 2; 11/99 Low-Cost, +2.
7V to +5.
5V, Micropower Temperature Switches in SOT23 and TO-220 ________________General Description 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 +115°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 activehigh, push-pull output intended to directly drive fancontrol logic.
The MAX6501/MAX6502 are offered with hot-temperature thresholds (+35°C to +115°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 5-pin SOT23 and 7-pin TO-220 packages.
