Product description
MCP9509/10 – Digital Temperature Sensor with Threshold Output
The MCP9509 is a digital temperature sensor from Microchip featuring an integrated comparator and factory-programmed temperature threshold. They operate over a temperature range of –40 °C to +125 °C and offer high accuracy without the need for external calibration. The output (push-pull or open-drain, depending on variant) switches logic state when the threshold is reached, making the sensor suitable for overtemperature protection and thermal control in embedded systems. Available in a compact SOT-23 package and easy to integrate.
