MICROCHIP TC72-3.3MUA

TC72 is a digital temperature sensor capable of reading temperatures from -65°C to +125°C. This sensor features a serial interface that allows communication with a host controller or other peripherals. The TC72 interface is compatible with the SPI protocol, and does not require any additional external components. However, it is recommended that a decoupling capacitor of 0.01μF to 0.1μF be provided between the VDD and GND pins. TC72 can be used either in a Continuous Temperature Conversion mode or a One-Shot Conversion mode. The Continuous Conversion mode measures the temperature approximately every 150 ms and stores the data in the temperature registers. In contrast, the One-Shot mode performs a single temperature measurement and returns to the power saving shutdown mode. TC72 features high temperature accuracy, ease-of-use and is the ideal solution for implementing thermal management in a variety of systems. The device is available in both 8-pin MSOP and 8-pin DFN spacesaving packages. TC72 also features a Shutdown mode for low power operation.
