Low-Cost, Remote SOT Temperature Switches
MAX6511/MAX6512/MAX6513
General Description
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.
Accuracy is within ±3°C (TA = -5°C to +55°C) or ±5°C (TA = -40°C to +85°C).
Hysteresis is pin selectable to 5°C or 10°C.
The MAX6511 has an active-low CMOS output and the MAX6513 has an active-high CMOS output.
