MAX6509/MAX6510

Resistor-Programmable

SOT Temperature Switches

________________________________________________________________ Maxim Integrated Products 1

19-1617; Rev 1b; 9/00

________________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°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.
