MCP9802A0T-M/OT

The MCP9802A0T-M/OT is a Digital Temperature Sensor capable of reading temperatures from -55 to 125°C. Temperature data is measured from an integrated temperature sensor and converted to digital word with an user selectable 9 to 12-bit sigma delta analogue to digital converter. The MCP9802A0T-M/OT notifies the host controller when the ambient temperature exceeds an user programmed set point. The ALERT output is programmable as either a simple comparator for thermostat operation or as a temperature event interrupt. Communication with the sensor is accomplished via a two-wire bus that is compatible with industry standard protocols. This permits reading the current temperature, programming the set point and hysteresis and configuring the device. The MCP9802A0T-M/OT also contains SMBus timeout logic for improved system reliability.
