MAX6513：Low-Cost, Remote SOT Temperature Switch

Industry's Only Temperature Switch for External P-N Junction - Either a Discrete Diode-Connected Transistor on an External IC Die

The MAX6513 is a fully integrated, remote temperature switch that uses an external P-N junction (typically a diode-connected transistor) as the sensing element to measure the remote temperature. The device asserts 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 MAX6513 has an active-high CMOS output. The output is asserted when the temperature exceeds the threshold value. The active-high CMOS output can directly drive a power FET to control a cooling fan. The MAX6513 operates from a +3.0V to +5.5V supply and typically consumes 400µA of supply current. It is available in a 6-pin lead-free TDFN package.
