MAX6639 Evaluation Kit  
Evluates:/MAX639F  
General Description  
Features  
o Two Thermal-Diode Inputs  
o Local Temperature Sensor  
o Programmable Temperature Alarms  
o Two PWM Outputs for Fan Drive  
The MAX6639 evaluation kit (EV kit) is an assembled and  
tested PCB used to evaluate the MAX6639 dual tempera-  
ture sensor/fan controller. The MAX6639 monitors its own  
die temperature and the junction temperature of one  
external diode-connected transistor, or the junction tem-  
peratures of two external diode-connected transistors. It  
converts the temperature to 8-bit or 11-bit 2-wire serial  
data that can be accessed over a 2-wire serial bus.  
o Up to 25kHz PWM Output Frequency  
o Programmable Fan-Control Characteristics  
o 3-Wire and 4-Wire Fan Configurations  
o On-Board Microcontroller to Generate  
The MAX6639 EV kit includes both external diode-connect-  
ed transistors (2N3906) soldered to the board, which can  
be bypassed to connect the board through a twisted pair  
to remote diodes close to your system.

SMBus™/I C Commands  
o USB-PC Connection (Cable Included)  
o Windows 2000/XP- and Windows Vista  
The temperature data is also used by the internal dual  
PWM fan-speed controller to adjust the speed of up to  
two cooling fans. Speed control is accomplished by  
tachometer feedback from the fan.  
The EV kit also includes Windows® 2000/XP- and  
Windows Vista®-compatible software, which provides a  
simple user interface for exercising the features of the  
MAX6639. The program is menu-driven and offers a  
graphical user interface (GUI) complete with control but-  
tons. The EV kit comes with the MAX6639AEE+ installed.  
Contact the factory for free samples of the pin-compatible  
MAX6639FAEE+ and MAX6640AEE+.  
(32-Bit)-Compatible Software  
o Easy-to-Use, Menu-Driven Software  
o Lead(Pb)-Free and RoHS Compliant  
o Fully Assembled and Tested
