MAX6510：Resistor-Programmable SOT Temperature Switches

Resistor-Programmable Temp Comparators in a SOT23!

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 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 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 are available in 5-pin and 6-pin SOT23 packages, respectively.
