Thermal Management datasheet and documents for MAX6639FATE+

MAX6639FATE+

Thermal Management Overview

The MAX6639FATE+ is a 2-channel temperature monitor with dual automatic PWM fan-speed controllers. It operates from 3.0V to 3.6V in a 16-pin TQFN-EP package. The device monitors its own die temperature and up to two external diode-connected transistors, providing 1°C remote accuracy optimized for n=1.021 Penryn compatibility. It features an SMBus interface, three programmable alarm outputs (OT, THERM, ALERT), and tachometer feedback for precise fan speed regulation.

Thermal Management Feature Summary

Dual thermal-diode inputs for remote monitoring of CPU or GPU temperatures
Integrated dual-PWM fan-speed controller with tachometer feedback for closed-loop RPM control
Three selectable SMBus slave addresses for multi-device system integration
Automatic fan spin-up capability ensures reliable cooling startup

Thermal Management Applications

Desktop computers
Notebook computers
Servers
Networking equipment

Thermal Management Procurement Notes

Verify the specific suffix 'FATE+' against the manufacturer's current ordering guide to confirm the exact package type and temperature range specifications. Ensure the design supports the required 3.0V to 3.6V supply voltage and SMBus communication protocols. Confirm that the exposed pad connection to ground is implemented correctly for thermal dissipation.

Thermal Management Selection Notes

Select this component when Penryn-compatible remote diode accuracy (n=1.021) is required for processor thermal management. Choose the TQFN-EP package for applications needing enhanced thermal performance and smaller footprint compared to QSOP variants. Ensure the system utilizes fans compatible with open-drain PWM drive signals pulled up to appropriate voltages.

Thermal Management Part Context

This part belongs to the MAX6639 family of hardware monitors. The 'F' designation indicates optimization for n=1.021 remote diode characteristics, suitable for Intel Penryn architecture processors. The 'A' denotes the -40°C to +125°C operating range, while 'TE' specifies the 16-pin thin QFN package with an exposed pad.
