General Description
The TC74 is a serially accessible, digital temperature sensor particularly
suited for low cost and small form factor applications. Temperature data is
converted from the onboard thermal sensing element and made available as an
8-bit digital word.
Communication with the TC74 is accomplished via a 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. During normal operation, the quiescent current is 200
µA (typ). During standby operation, the quiescent current is 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.
