________________General Description
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癈 to +125癈 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 ?.5癈 (typ) or ?.7癈 (max). They typically con-
sume 32礎 supply current. Hysteresis is pin selectable
to 2癈 or 10癈.
The MAX6509/MAX6510 are available in 5-pin and 6-pin
SOT23 packages, respectively.
