The Microchip Technology MCP9843-BE/ST is a digital temperature sensor designed for accurate temperature monitoring. It converts temperature readings from -40°C to +125°C into a digital word, meeting JEDEC specifications for thermal sensing components.
This sensor features a 2-wire I2C/SMBus interface, allowing for easy integration into various systems. It provides a temperature accuracy of ±0.2°C/±1°C (typical/maximum) in the +75°C to +95°C range. The device operates within a voltage range of 2.7V to 5.5V and consumes a typical operating current of 200 µA.
The MCP9843/98243 series includes user-programmable registers for flexible configuration, such as setting shutdown or low-power modes and defining temperature event boundaries. An Alert signal is output when temperature limits are exceeded, configurable as an active-low or active-high comparator output or as a temperature event interrupt.
Available in an 8-TSSOP package, the MCP9843-BE/ST is suitable for surface mount applications. The MCP98243 variant includes a 2 Kbit Serial EEPROM for storing memory module and vendor information, particularly for DIMM modules in servers, PCs, and laptops.
