Thermal Sensor with SPIInterface  
Features  
Description  
• Digital Temperature Sensing in 5-Pin SOT-23A  
The TC77 is a serially accessible digital temperature  
sensor particularly suited for low cost and small form-  
factor applications. Temperature data is converted from  
the internal thermal sensing element and made avail-  
able at anytime as a 13-bit two’s compliment digital  
word. Communication with the TC77 is accomplished  
via a SPI and MICROWIRE compatible interface. It has  
a 12-bit plus sign temperature resolution of 0.0625°C  
per Least Significant Bit (LSb). The TC77 offers a tem-  
perature accuracy of ±1.0°C (max.) over the tempera-  
ture range of +25°C to +65°C. When operating, the  
TC77 consumes only 250 µA (typ.). The TC77’s Con-  
figuration register can be used to activate the low  
power Shutdown mode, which has a current consump-  
tion of only 0.1 µA (typ.). Small size, low cost and ease  
of use make the TC77 an ideal choice for implementing  
thermal management in a variety of systems.
