The MAX6509/MAX6510 are fully integrated, resistor-
programmable temperature switches with thresholds
set by an external resistor. They require only one exter-
nal resistor to set the temperature threshold within a
wide -40°C to +125°C temperature range. The MAX6509
provides 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 accura-
cy of ±0.5°C (typ) or ±4.7°C (max). They typically con-
sume 32µA supply current. Hysteresis is pin selectable
to 2°C or 10°C.
The MAX6509/MAX6510 are available in 5-pin and 6-pin
SOT23 packages, respectively.
