Description

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.
