EMC2103-2-AP-TR

Thermal Management Overview

The EMC2103-2-AP-TR is an SMBus-compliant fan controller featuring up to three external and one internal temperature channel. It supports a 4-wire fan driver with high and low frequency PWM drive settings. The device includes an RPM-based fan speed control algorithm with 2.5% accuracy from 500RPM to 16k RPM, alongside a programmable temperature look-up table for automated thermal management. Hardware programmable thermal shutdown limits range from 65°C to 127°C. It operates on a 3.3V supply voltage and is housed in a 16-pin QFN package.

Thermal Management Feature Summary

• Supports RPM-based fan control algorithm with hardware thermal shutdown
• Includes temperature look-up table for automated fan response
• Features up to three external temperature channels with resistance error correction
• Provides two dedicated GPIOs

Thermal Management Applications

• Notebook Computers
• Projectors
• Graphics Cards
• Industrial and Networking Equipment

Thermal Management Procurement Notes

Verify the specific suffix 'AP' against the manufacturer's official documentation to confirm EEPROM load configuration status. Ensure compatibility with the required 16-pin QFN footprint during PCB layout. Confirm that the selected component meets the necessary RoHS compliance standards for your target market regulations before finalizing procurement orders.

Thermal Management Selection Notes

Select this component when hardware-level thermal protection is required independent of software intervention. It is suitable for designs needing precise RPM monitoring and automatic fan speed adjustment based on multiple temperature sources. Consider the 16-pin QFN package constraints and ensure adequate thermal dissipation paths are designed into the system layout.

Thermal Management Part Context

This part belongs to the EMC2103 family of SMBus fan controllers. The -2 variant specifically provides support for up to three external diodes and includes two general-purpose input/output pins. It shares core features like the RPM algorithm and hardware shutdown logic with other members of the series but differs in pin count and peripheral availability.

Thermal Management Replacement Considerations

The EMC2103-4-AP-TR is a confirmed substitute offering identical functionality with enabled EEPROM loading capabilities.
