General Description
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.
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.
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+.
The MAX6639 EV kit also evaluates the MAX6640. The
MAX6640 is not recommended for new designs.
