Thermal Management datasheet and documents for MAX6639AEE+T

MAX6639AEE+T

Thermal Management Overview

The MAX6639AEE+T is a board-mount temperature sensor and hardware monitor in a 16-pin QSOP package. It operates from a 3.0V to 3.6V supply with 500µA current consumption. The device features an 11-bit resolution, ±1°C remote accuracy, and supports SMBus/I2C interfaces. It monitors local and two external diode temperatures up to +150°C.

Thermal Management Feature Summary

Dual PWM fan-speed controller with tachometer feedback for closed-loop speed regulation
SMBus interface for programmable alarm thresholds and register access
Automatic fan spin-up and controlled rate-of-change for unobtrusive adjustments
Dedicated outputs for thermal throttling (THERM) and overtemperature shutdown (OT)

Thermal Management Applications

Desktop Computers
Notebook Computers
Servers
Networking Equipment

Thermal Management Procurement Notes

Verify the specific suffix 'AEE' indicates the standard n=1.008 calibration variant, distinct from the 'F' series optimized for Penryn compatibility. Confirm the '+T' designation corresponds to reel packaging as listed in official ordering information. Ensure the component meets RoHS compliance standards required for the target assembly process.

Thermal Management Selection Notes

Select this component when dual-channel remote monitoring and integrated fan control are required within a single IC. The MAX6639AEE is suitable for systems needing precise CPU/GPU thermal management without external microcontrollers. Consider the MAX6639FAEE+T if Penryn-specific calibration parameters are necessary for the application.

Thermal Management Part Context

Part of the MAX6639 family of 2-channel temperature monitors. The MAX6639AEE variant provides standard diode calibration, whereas the MAX6639FAEE variant is optimized for n=1.021 compatibility. Both share identical pinouts and functional blocks but differ in measurement accuracy specifications for specific transistor types.
