ActiveTEMPERATURE SENSOR DIGITAL SERIAL (2-WIRE, I2C, SMBUS) 5-PIN SOT-23 T/R
Description
General part information
TC74 Series
TC74 is a serially accessible digital temperature sensor particularly suited for low cost and small form-factor applications. Temperature data is converted from the on-board thermal sensing element and made available as an 8-bit digital word. 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. Temperature resolution is 1°C. Conversion rate is a nominal 8 samples/sec. Power consumption in only 200 µA (5 µA Standby). Small size, low installed cost and ease of use make the TC74 an ideal choice for implementing thermal management in a variety of systems.
