The MCP9509/10 series of temperature switches are controlled by an external resistor with various programmable options such as switch hysteresis and output structure configurations. This enables the designer to customize their temperature control applications according to their requirements.
Typical applications include temperature alarms, thermostat controls, fan control, base-stations, automotive and power supply thermal shut-down.
