Accurate Temperature Sensor MICROCHIP MCP9804-E/MC Featuring Digital Output and Programmable Alert Limits

Product Overview

The Microchip Technology Inc. MCP9804 is a digital temperature sensor that converts temperatures between -40C and +125C to a digital word with 0.25C/1C (typical/maximum) accuracy. It features user-programmable registers for flexibility, allowing settings like Shutdown or Low-Power modes, and user-defined temperature Alert window limits and critical output limits. The MCP9804 outputs an Alert signal when temperature boundaries are exceeded and offers configurable Alert output polarity (active-low or active-high) for thermostat or interrupt applications. Its industry-standard 100 kHz, 2-wire, SMBus/I2C compatible serial interface supports up to sixteen sensors on a single bus, making it ideal for sophisticated, multi-zone temperature monitoring. Applications include general purpose, industrial, food processing, personal computers and servers, PC peripherals, consumer electronics, and handheld/portable devices.
