TC74
Tiny Serial Digital Thermal Sensor
Features General Description Digital Temperature Sensing in SOT-23-5 or
TO-220 Packages Outputs Temperature as an 8-Bit Digital Word Simple SMBus/I2Cв„ў Serial Port Interface Solid-State Temperature Sensing:
-В±2В°C (max.) Accuracy from +25В°C to +85В°C
-В±3В°C (max.) Accuracy from 0В°C to +125В°C Supply Voltage of 2.7V to 5.5V Low Power:
-200 ВµA (typ.) Operating Current
-5 ВµA (typ.) Standby Mode Current The TC74 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 as an 8-bit digital word. Applications Thermal Protection for Hard Disk Drives
and other PC Peripherals PC Card Devices for Notebook Computers Low Cost Thermostat Controls Power Supplies Thermistor Replacement Package Types Communication with the TC74 is accomplished via a 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 1В°C. Conversion rate is a
nominal 8 samples/sec. During normal operation, the
quiescent current is 200 ВµA (typ). During standby
operation, the quiescent current is 5 ВµA (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. Functional Block Diagram Internal Sensor
