MAX6509/MAX6510
Resistor-Programmable
SOT Temperature Switches
General Description
The MAX6509/MAX6510 are fully integrated, resistor-
programmable temperature switches with thresholds set
by an external resistor. They require only one external
resistor to set the temperature threshold within a wide
-40°C to +125°C temperature range. The MAX6509 pro-
vides an open-drain output. The MAX6510 features three
selectable output options: active-low, active-high, and
open drain with an internal pull-up resistor.
These switches operate with a +2.7V to +5.5V single
supply while providing a temperature threshold accuracy
of ±0.5°C (typ) or ±4.7°C (max). They typically consume
32µA supply current. Hysteresis is pin selectable to 2°C
or 10°C.
The MAX6509/MAX6510 re available in 5-pin and 6-pin
SOT23 packages, respectively.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
