Microchip Temperature Sensor Switch, Open Drain Output, Surface Mount, ±6°C, 5 Pins

The MCP9501/2/3/4 series of temperature switches feature factory-set temperature thresholds, selectable switch hysteresis and a variety of output configurations for use in temperature alarm, thermostat control, fan control, automotive, base-station and power supply critical temperature shut-down applications.

MCP9501: Has an active-low, open-drain output suitable for hot temperatures.

MCP9502: Has an active-high, push-pull output suitable for hot temperatures.

MCP9503: Has an active-low, open-drain output suitable for cold temperatures.

MCP9504: Has an active-high, push-pull output suitable for cold temperatures.

The Microchip MCP9501 temperature switch with ±1°C (typical) accurate factory set output thresholds is ideal for high power supply systems where an Overtemperature protection circuit is needed. It operates on voltage range of 2.7V to 5.5V. This switch does not require external components, consume 25 μA (typical), and the factory set thresholds provide simplicity.
