MCP9804T-E/MCVAO

The MCP9804T-E/MCVAO digital temperature sensor converts temperatures between -40°C and +125°C to a digital word with ±1°C (max.) accuracy.The MCP9804T-E/MCVAO comes with user-programmable registers that provide flexibility for temperature sensing applications.The registers allow user-selectable settings such as Shutdown or low-power modes and the specification of temperature Event and Critical output boundaries. When the temperature changes beyond the specified boundary limits, the MCP9804T-E/MCVAO outputs an Event signal. The user has the option of setting the event output signal polarity as an active-low or active-high comparator output for thermostat operation, or as temperature event interrupt output for microprocessor-based systems. The event output can also be configured as a Critical temperature output.This sensor has an industry standard 2-wire, SMBus and Standard I2C™Compatible compatible (100kHz/400kHz bus clock) serial interface, allowing up to eight sensors to be controlled in a single serial bus. These features make the MCP9804T-E/MCVAO ideal for sophisticated multi-zone temperature- monitoring applications.
