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.
