TC77 Datasheet Docket ↓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 MICROWIREâ„¢ 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.
