MAXIM MAX6512UT105

The MAX6511/MAX6512/MAX6513 are fully integrated, remote temperature switches that use an external P-N junction (typically a diode-connected transistor) as the sensing element to measure the remote temperature. These devices assert a logic signal when the temperature crosses a factory-programmed threshold. Available trip thresholds are from +45°C to +125°C in 10°C increments.
