EMC6D103-CZC-TR

Thermal Management Overview

The EMC6D103-CZC-TR is a fan control device featuring high-frequency PWM support and hardware monitoring capabilities. It operates at 3.3 volts with 5-volt tolerant input buffers and utilizes an SMBus 2.0 compliant interface offering three selectable slave address options. The component provides three PWM outputs, four fan tachometer inputs, and supports programmable automatic fan control based on temperature. It includes two remote thermal diode monitoring channels with specified accuracy, internal ambient temperature measurement, and voltage monitoring for multiple power supplies.

Thermal Management Feature Summary

• Supports high-frequency PWM drive for 4-wire fans while maintaining backward compatibility with lower frequency requirements.
• Enables one fan to be controlled from up to three distinct temperature zones with configurable ramp rates for acoustic noise reduction.
• Provides hardware monitoring of two remote thermal diodes and internal ambient temperature with limit comparison and interrupt generation.

Thermal Management Applications

• Server and workstation chassis cooling management
• Industrial equipment thermal regulation
• High-density electronic system ventilation control

Thermal Management Procurement Notes

Verify the specific ordering suffix '-TR' confirms tape and reel packaging when sourcing components. Confirm that the fixed, non-discoverable SMBus interface aligns with the host controller's addressing scheme. Ensure the 3.3V operation requirement matches the system logic levels, noting the 5V tolerance of input buffers.

Thermal Management Selection Notes

Select this component when precise thermal management requires linking multiple temperature sensors to individual fan outputs. Consider its capability for continuous or cycling monitoring modes to optimize power consumption in standby states. Evaluate the need for hardware-based voltage and temperature limit comparisons to reduce host processor overhead.

Thermal Management Part Context

This device belongs to the SMSC EMC6D103 series, designed specifically for managing thermal environments in computing systems. It integrates fan speed control and hardware monitoring into a single package, reducing the complexity of system design by handling critical thermal tasks independently of the main processor.
