EMC2112-BP-TR

Thermal Management Overview

The EMC2112-BP-TR is an SMBus, closed-loop, RPM-based fan driver with hardware thermal shutdown and reset controller capabilities. It features a single high-side fan driver capable of sourcing up to 600mA from a 5V supply. The device utilizes Beta Compensation and Resistance Error Correction (REC) to accurately monitor up to three external temperature zones. It operates from a single 3.0V to 3.6V supply for logic and uses a 5V supply for the linear fan driver and reset generator. The component supports user-selectable SMBus addresses via the ADDR_SEL pin.

Thermal Management Feature Summary

Closed-loop RPM-based fan control algorithm with aging detection
Integrated linear fan driver with 600mA drive capability
Hardware thermal shutdown block with 1°C incremental set points
Supports up to three remote thermal zones with resistance error correction

Thermal Management Procurement Notes

Verify the specific ordering suffix BP-TR against the manufacturer's current documentation to confirm package type and reel specifications. Ensure compatibility with the required SMBus address configuration using the ADDR_SEL pin pull-up resistor. Confirm that the design accommodates the 20-pin QFN footprint and the necessary discrete components for the TRIP_SET pin to define the critical temperature limit.

Thermal Management Selection Notes

Select this component when a closed-loop fan control solution requiring hardware thermal protection is needed. It is suitable for systems utilizing CPU substrate thermal diodes or discrete diode-connected transistors across multiple process geometries. Consider its ability to eliminate temperature offset due to series resistance in PCB traces when designing for high accuracy in multi-zone thermal monitoring applications.

Thermal Management Part Context

The EMC2112 is part of the SMSC product line, now under Microchip Technology. It serves as a dedicated thermal management IC designed to replace complex discrete solutions for fan speed control and system reset generation. The device integrates both analog sensing features and digital interface protocols into a compact form factor.
