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 tempera-
ture crosses a factory-programmed threshold. Available
trip thresholds are from +45°C to +125°C in 10°C incre-
ments. Accuracy is within ±3°C (T
A
= -5°C to +55°C) or
±5°C (T
A
= -40°C to +85°C). Hysteresis is pin selec-
table 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. The active-low open-drain output is intended to
interface with a microprocessor (μP) reset or interrupt
input. The active-high CMOS output can directly drive a
power FET to control a cooling fan.
The MAX6511/MAX6512/MAX6513 operate from a
+3.0V to +5.5V supply and typically consume 400μA of
supply current. They are available in a small 6-pin
SOT23 package.
