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.
