MCP9803-M/SN - Microchip Function Overview

The MCP9803-M/SN 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 MCP9803 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. Address selection inputs allow up to eight MCP9803 sensors to share the same 2-wire bus for multizone monitoring. The MCP9803 also contains SMBus timeout logic for improved system reliability.
