The MAX6639FAEE+ from Analog Devices is a versatile 2-channel temperature monitor IC with an integrated dual PWM fan-speed controller. This device can monitor its own temperature and the temperatures of two external diode-connected transistors, commonly found in CPUs, FPGAs, or GPUs.
Key features include 1°C remote temperature accuracy and a sensing temperature range of 0°C to 150°C. The operating voltage range is from 3.0V to 3.6V, with a typical supply current of 500µA. The IC communicates via a 2-wire serial interface supporting standard SMBus commands.
Designed for applications like desktop computers, notebook computers, projectors, servers, and networking equipment, the MAX6639FAEE+ offers programmable alarm outputs for interrupts or shutdown signals. It also provides automatic fan spin-up and controlled rate-of-change for unobtrusive fan-speed adjustments, with fan-speed measurement accuracy of ±3%.
The MAX6639FAEE+ is available in a 16-pin QSOP package, suitable for surface mount applications. It operates within an ambient temperature range of -40°C to 125°C.
