Microchip Technology TC74A1-5.0VCTTR - Digital Temperature Sensor

The TC74A1-5.0VCTTR is a precision digital temperature sensor from Microchip Technology, offering a simple yet effective solution for thermal management within electronic systems. This sensor is designed to provide accurate temperature readings with a digital output, making it ideal for a wide range of applications such as industrial systems, consumer electronics, and computer peripherals.

Featuring a temperature range from -40°C to +125°C, the TC74A1-5.0VCTTR ensures reliable performance across diverse operating conditions. The sensor communicates via a two-wire, I2C-compatible serial interface, which simplifies integration into existing designs and allows for multiple sensors to be connected on the same bus for monitoring different locations.

The device operates from a single supply voltage of 5.0V, making it compatible with many standard systems without the need for additional voltage regulation. Its low operating current of just 200 µA (typical) during active conversions, and a 5 µA (typical) standby current help to minimize power consumption, making it an energy-efficient choice for battery-powered applications.

With its small SOT-23-5 package, the TC74A1-5.0VCTTR is designed for space-constrained applications. It also offers excellent thermal tracking, ensuring that the temperature reading closely follows the actual temperature of the device or system being monitored. The sensor provides a digital output in the form of a 9-bit word, corresponding to the temperature it senses, with an accuracy of ±2°C.
