MICROCHIP TC77-5.0MCTTR

The TC77-5.0MCTTR is a Thermal Sensor with SPI interface. The TC77 is a serially accessible digital temperature sensor particularly suited for small form-factor 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°C per Least Significant Bit (LSb). The TC77 offers a temperature accuracy of ±1.0°C (maximum) over the temperature range of +25 to +65°C. When operating, the TC77 consumes only 250μA (typical). The TC77's configuration register can be used to activate the low power shutdown mode, which has a current consumption of only 0.1μA (typical). Small size and ease of use make the TC77 an ideal choice for implementing thermal management in a variety of systems.
