Microchip Technology, Inc. Sensors, Transducers - Temperature Sensors - Thermostats - Solid State TC621HEPA

The TC621HEPA is a solid-state temperature sensor designed for thermal management applications. It operates within a temperature range of -40¬8C to +85¬8C and features user-programmable hysteresis and temperature set points, allowing for flexibility in various applications. The device utilizes an external NTC thermistor for remote sensing, making it suitable for applications requiring precise temperature monitoring. It provides dual thermal interrupt outputs for over-temperature and under-temperature conditions, which can be configured using external resistors. The TC621HEPA is available in an 8-PDIP package and has a supply voltage range of 4.5V to 18V, with a typical supply current of 270¬µA. The output function is active low, with a maximum output current of 1mA. The accuracy of the temperature measurement is ¬±3¬8C, making it a reliable choice for applications such as power supply over-temperature detection and CPU thermal protection.
