The TC74A5-5.0VCTTR from Microchip Technology is a serially accessible digital temperature sensor designed for low-cost and small form-factor applications. It outputs temperature data as an 8-bit digital word via a 2-wire SMBus/I2C compatible serial port. This sensor offers solid-state temperature sensing with an accuracy of ±2°C from +25°C to +85°C and ±3°C from 0°C to +125°C.
Key electrical characteristics include a supply voltage range of 2.7V to 5.5V. The device features low power consumption, with a typical operating current of 200 µA and a standby mode current of 5 µA. Temperature resolution is 1°C, and the conversion rate is nominally 8 samples/sec.
Packaged in a SOT-23-5 surface mount package, the TC74A5-5.0VCTTR is suitable for various applications requiring thermal management. Its small size and ease of use make it an ideal choice for thermal protection in hard disk drives, PC card devices, power supplies, and thermostat controls, serving as a thermistor replacement.
This sensor is designed for applications requiring precise temperature monitoring. Its digital output simplifies integration into microcontroller-based systems, and the SMBus/I2C interface allows for multi-drop configurations for monitoring multiple zones. The SHDN bit in the CONFIG register enables a low-power standby mode, further enhancing its suitability for power-sensitive designs.
