2-Channel Temperature Monitor with Dual,  
Automatic, PWM Fan-Speed Controller  
General Description  
Features  
The MAX6639 monitors its own temperature and one  
external diode-connected transistor or the temperatures  
of two external diode-connected transistors, typically  
available in CPUs, FPGAs, or GPUs. The 2-wire serial  
interface accepts standard System Management Bus  
(SMBusTM) write byte, read byte, send byte, and  
receive byte commands to read the temperature data  
and program the alarm thresholds. Temperature data  
can be read at any time over the SMBus, and three pro-  
grammable alarm outputs can be used to generate  
interrupts, throttle signals, or overtemperature shut-  
down signals.  
♦ 2 Thermal-Diode Inputs  
♦ Up to 25kHz PWM Output Frequency  
♦ 3 Selectable SMBus Addresses  
♦ Local Temperature Sensor  
♦ 1°C Remote Temperature Accuracy  
♦ Two PWM Outputs for Fan Drive (Open Drain; Can  
be Pulled Up to +13.5V)  
♦ Programmable Fan-Control Characteristics  
♦ Automatic Fan Spin-Up Ensures Fan Start  
The temperature data is also used by the internal dual-  
PWM fan-speed controller to adjust the speed of up to  
two cooling fans, thereby minimizing noise when the  
system is running cool, but providing maximum cooling  
when power dissipation increases. Speed control is  
accomplished by tachometer feedback from the fan, so  
that the speed of the fan is controlled, not just the PWM  
duty cycle. Accuracy of speed measurement is 4%.  
♦ Controlled Rate-of-Change Ensures Unobtrusive  
Fan-Speed Adjustments  
♦
3ꢀ Fan-Speed Measurement Accuracy  
♦ Temperature Monitoring Begins at POR for Fail-  
Safe System Protection  
♦ OT and THERM Outputs for Throttling or  
The MAX6639 is available in 16-pin QSOP and 16-pin  
TQFN 5mm x 5mm packages. It operates from 3.0V to  
5.5V and consumes just 500µA of supply current.
