Thermal Management datasheet and documents for EMC2102-DZK

EMC2102-DZK

Thermal Management Overview

The EMC2102-DZK is an SMBus, closed-loop, RPM-based fan controller and driver featuring hardware thermal shutdown. It integrates a linear fan driver capable of sourcing 600mA and supports fans operating up to 16,000 RPMs. The device monitors three external temperature zones with ±1°C accuracy using Beta Compensation and Resistance Error Correction. It operates from a single 3.0V to 3.6V supply for logic and a separate 5V supply for the fan driver.

Thermal Management Feature Summary

Thermal Management Procurement Notes

Verify the component origin as SMSC or its subsidiaries, noting that Microchip Technology acquired SMSC assets. Confirm the package type is a 28-pin, 5x5mm QFN lead-free RoHS compliant variant. Ensure the specific ordering suffix matches the address code 011_1101 for the DZK designation.

Thermal Management Selection Notes

Select this component when precise RPM-based fan regulation and independent hardware thermal protection are required. It is suitable for systems utilizing CPU substrate thermal diodes across various process geometries. The dual-supply architecture isolates the fan driver power from the logic supply.

Thermal Management Part Context

This part belongs to the EMC2102 series of fan controllers. It is manufactured by Microchip Technology following the acquisition of Standard Microsystems Corporation (SMSC). The datasheet revision is 2.02, dated May 17, 2007.
