MCP9844T-BE/MNY

The MCP9844T-BE/MNY is a Digital Temperature Sensor that converts temperature from -40 to +125°C to a digital word. The device 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 boundaries. When the temperature changes beyond the specified event boundary limits, the MCP9844 outputs an alert signal at the event pin. The user has the option of setting the temperature event output signal polarity as either an active-low or active-high comparator output for the thermostat operation or as a temperature event interrupt output for microprocessor-based systems. This sensor has an industry standard I²C fast mode plus compatible 1MHz serial interface.
