    TC77
    Thermal Sensor with SPI Interface
    Features Description Digital Temperature Sensing in 5-Pin SOT-23A
    and 8-Pin SOIC Packages Outputs Temperature as a 13-Bit Digital Word SPI and MICROWIRE™ Compatible Interface Solid State Temperature Sensing ±1°C (max.) accuracy from +25°C to +65°C ±2°C (max.) accuracy from -40°C to +85°C ±3°C (max.) accuracy from -55°C to +125°C 2.7V to 5.5V Operating Range Low Power
    -250 µA (typ.) Continuous Conversion Mode
    -0.1 µA (typ.) Shutdown Mode 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°C
    per Least Significant Bit (LSb). The TC77 offers a temperature accuracy of ±1.0°C (max.) over the temperature range of +25°C to +65°C. 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. Typical Applications Thermal Protection for Hard Disk Drives and
    Other PC Peripherals PC Card Devices for Notebook Computers Low Cost Thermostat Controls Industrial Control Office Equipment Cellular Phones Thermistor Replacement Package Types
