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 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.

FEATUREs
♦ ±0.5°C Threshold Accuracy
♦ ±4.7°C (max) Threshold Accuracy (-40°C to +125°C)
♦ Temperature Threshold Set by a 1% External Resistor
♦ Set-Hot or Set-Cold Option
♦ Low 32µA Supply Current
♦ Open-Drain, Push-Pull Outputs; Open-Drain with Internal Pull-Up Resistor
♦ Pin-Selectable 2°C or 10°C Hysteresis
♦ SOT23 Packages
