Product Introduction
The TC77 is a serially accessible digital temperature sensor particularly suited for low cost and small formfactor applications. Temperature data is converted from the internal thermal sensing element and made available 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℃ per Least Significant Bit (LSb). The TC77 offers a temperature accuracy of ±1.0 (max.) over the temperature range of +25℃ to +65℃. When operating, the TC77 consumes only 250 μA (typ.). The TC77’s Configuration register can be used to activate the low power Shutdown mode, which has a current consumption 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.
