TC77具有SPI接口的热传感器
分享资料个
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.
