EMC2106-DZK-TR

Thermal Management Overview

The EMC2106-DZK-TR is a System Management Bus (SMBus) compliant fan controller manufactured by Microchip Technology, originally developed by SMSC. It features two independent fan control circuits: a high-side driver and a linear DAC driver. The device supports up to five temperature channels, including four external diodes and one internal thermal shutdown input. It incorporates an RPM-based fan speed control algorithm with hardware programmable thermal limits and dedicated system shutdown outputs for critical circuitry protection.

Thermal Management Feature Summary

• Dual fan drivers supporting both high-side PWM and linear DAC modes
• RPM-based fan speed control algorithm with automatic aging detection
• Hardware programmable thermal shutdown with dedicated output
• Temperature monitoring with resistance error correction and beta compensation

Thermal Management Applications

• Notebook Computers
• Embedded Applications
• Projectors
• Industrial and Networking Equipment

Thermal Management Procurement Notes

Verify the specific ordering suffix '-TR' indicates tape and reel packaging configuration. Confirm that the component retains the original SMSC designation or branding as documented in the datasheet revision history. Ensure compatibility with SMBus 2.0 protocols and verify the 28-pin QFN package dimensions against current design requirements.

Thermal Management Selection Notes

Select this component when dual independent fan control is required alongside comprehensive thermal management. The inclusion of both high-side and linear drivers allows flexibility in driving different fan types. The hardware thermal shutdown feature provides a reliable safety mechanism independent of software operation, suitable for critical infrastructure applications.

Thermal Management Part Context

The EMC2106 series was originally produced by Standard Microsystems Corporation (SMSC). Following industry consolidation, these products are now managed under the Microchip Technology portfolio. The device represents a specialized solution for thermal management in compact electronic systems requiring precise fan speed regulation and robust temperature monitoring capabilities.

Thermal Management Replacement Considerations

Check for updated Microchip part numbers if the original SMSC designation is discontinued. Verify pinout compatibility and register map alignment before substituting with other SMBus fan controllers from different manufacturers.
