The is a serially accessible, digital temperature sensor particularly suited for low cost and small formfactor applications. Temperature data is converted from the onboard thermal sensing element and made available an 8-bit digital word. Communication with the TC74 is accomplished via 2wire 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. During normal operation, the quiescent current 200 µA (typ). During standby operation, the quiescent current 5 µA (typ). Small size, low installed cost and ease of use make the TC74 an ideal choice for implementing thermal management in a variety of systems.
