Product Description
Microchip TCN75 is a highly accurate surface mount temperature sensor featuring ±0.5 °C typical accuracy and an 8-pin SOIC package. Designed for robust temperature monitoring and control, it communicates over a 2-wire serial bus compatible with standard protocols.
This device operates across a wide temperature range from -55 °C up to +125 °C, making it suitable for diverse industrial, commercial, and HVAC applications. The sensor is fully programmable for temperature trip point and hysteresis, allowing precise temperature threshold detection and control tailored to specific needs.
The INT/CMPTR output can be configured as a simple comparator to emulate thermostat behavior or as an interrupt for signaling thermal events, enhancing system integration flexibility. With the capacity to connect up to 8 TCN75 sensors on the same bus, it supports complex multi-point temperature sensing architectures.
The device operates at a low supply current of approximately 250 microamperes, extending battery life in portable applications. The operating supply voltage ranges between 2.7 V to 5.5 V, with 5 V tolerant I/O pins when powered at 3 V, further adding versatility in electronic system design.
Its compact 8-pin SOIC package measures 5 mm in length, 3.1 mm in width, and 1.1 mm in height, ideal for surface mounting on densely packed circuits. The package is RoHS compliant, ensuring environmentally friendly manufacturing standards.
0.5 °C typical accuracy for precise temperature measurement. Wide temperature operating range from -55 °C to +125 °C. Programmable trip point and hysteresis with power-up defaults. 2-wire serial interface compatible with industry standards.
Thermal event alarm output configurable as interrupt or comparator. Low power consumption at 250 µA typical. Up to 8 sensors can share a single 2-wire bus. 5 V tolerant I/O pins at 3 V supply voltage. Compact SOIC package suitable for surface mount applications.
