EMC2101-R-ACZL-TR

Thermal Management Overview

The EMC2101-R-ACZL-TR is an SMBus 2.0 compliant fan control and temperature monitoring IC manufactured by Microchip Technology (formerly SMSC). It features selectable PWM or DAC fan driver outputs, an internal temperature monitor with ±2°C accuracy, and an external channel with ±1°C accuracy. The device supports automatic beta compensation and resistance error correction up to 100 Ω. It operates on a 3.3V supply with 5V tolerant I/O buffers and includes auto-programming capabilities via an attached SMBus compatible EEPROM upon power-up.

Thermal Management Feature Summary

Selectable PWM or Linear (DAC) fan drive output controlled by an eight-position look-up table
Integrated temperature monitoring with automatic beta compensation and resistance error correction
SMBus 2.0 interface supporting timeout functionality and auto-programming from external EEPROM

Thermal Management Applications

Graphics processors
Embedded application fan drive
PWM controller combined with temperature sensor

Thermal Management Procurement Notes

Verify the specific suffix 'R' indicates the version with auto-programming support from an attached SMBus compatible EEPROM. Confirm the package type matches the required board layout for the 8-pin MSOP lead-free RoHS compliant variant. Ensure the design accommodates the 3.3V operation voltage while respecting the 5V tolerance limits on input buffers.

Thermal Management Selection Notes

Select this component when system requirements include precise thermal management with programmable fan curves based on temperature thresholds. The choice between PWM and DAC output depends on the connected fan type and noise sensitivity. Consider the 'R' variant if hardware configuration persistence across power cycles via external EEPROM is necessary for the deployment environment.

Thermal Management Part Context

This part belongs to the EMC2101 family of SMBus fan controllers. The standard EMC2101 offers fixed PWM drive, whereas the EMC2101-R variant allows fan operation mode selection via pull-ups and supports self-programming. Both variants share similar thermal sensing capabilities and are designed for compact surface-mount applications in consumer and industrial electronics.
