Microchip | TC74A5-3.3VCTTR

Microchip Technology is a leading innovator and supplier of high performance and high quality embedded solutions and microcontrollers; related non-volatile memory products; and a broad analog product line focusing on power management, thermal management, linear and mixed-signal solutions.

Temperature sensing is critical to a growing number of consumer, automotive, and industrial applications. Microchip’s digital temperature sensors are ideal choice for implementing temperature system management schemes in a variety of applications.

TC74 - Tiny Serial Digital Thermal Sensor

TC74 is a serially accessible digital temperature sensor capable of reading temperatures from -40°C to +125°C and particularly suited for small form-factor applications.

Temperature data is converted from the on-board thermal sensing element and made available as an 8-bit digital word.  The TC74 has accuracy of ±2°C (max.) in the temperature range from +25°C to +85°C and ±3°C (max.) in the range from 0°C to +125°C.

The TC74 temperature resolution is 1°C. Conversion rate is a nominal 8 samples/sec. Power consumption in only 200 µA (5 µA Standby).

Communication with the TC74 is accomplished via a simple 2-wire SMBus/I2C™-compatible serial port. This bus also can be used to implement multi-drop/multi-zone monitoring. The SHDN bit in the CONFIG register can be used to activate the low-power Standby mode.

The TC74A5-3.3VCTTR is a SOT-23 Tiny Serial Digital Thermal Sensor with accuracy optimized for 3.3V that comes in 3000 piece reel.
