MAX6511 - Low-Cost / Remote SOT Temperature Switches

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.

Key Features

  • o Continuously Measure External Junction Temperature o Factory-Programmed Temperature Threshold from +45°C to +125°C in 10°C Increments o Insensitive to Series Parasitic Resistance o Active-Low CMOS Output (MAX6511) or OpenDrain Output for Overtemperature Alarm (MAX6512) or Active-High Output (MAX6513) for Direct Fan Control o.

19-1819; Rev 1; 11/03 Low-Cost, Remote SOT Temperature Switches 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. The MAX6512 has an open-drain output. The output is asserted when the temperature exceeds the threshold value.
