Overview

The EMC1813T-AE/UN is a high-accuracy, low-voltage SMBus temperature sensor capable of monitoring one internal and two remote temperature zones. It features advanced thermal management tools such as Resistance Error Correction (REC), Beta Compensation, and a unique Rate of Change calculation with preemptive alerts to detect rapid thermal shifts before they exceed critical thresholds.

Why Choose This Part

This sensor offers exceptional power efficiency with operating currents as low as 20uA and supports a wide supply voltage range from 1.62V to 3.6V. Its hardware-based Rate of Change alert provides a critical safety layer by identifying accelerating temperature rises that standard static limit alerts might miss.

Applications

Processor Thermal Monitoring
Utilizes remote diode sensing to monitor CPU or FPGA die temperatures with integrated resistance error correction.
Battery Pack Protection
Monitors multiple cells using remote thermistors or diodes to provide preemptive alerts for thermal runaway conditions.
Precision Industrial Instrumentation
Provides high-resolution temperature data for sensitive analog circuitry calibration in low-power environments.

Getting Started

Interface the device via its I2C/SMBus compatible serial port and configure the programmable limits for the ALERT and THERM pins. For rapid prototyping, use a standard MSOP-10 breakout board and refer to Microchip's SMBus communication libraries to implement the 11-bit temperature resolution readings.
