MAX6651 Evaluation Kit/Evaluation System
Procedure
The MAX6651 EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed.
1) Visit the Maxim website (www.maxim-ic.com/evkit-
software) to download the latest version of the EV
kit software, 6651Rxx.ZIP.
2) Install the MAX6651 evaluation software on your
computer by running the INSTALL.EXE program.
The program files are copied and icons are created
in the Windows Start menu.
3) On the CMAXQUSB board, ensure the shunt of
jumper JU1 is in the 5V position.
4) Carefully connect the boards by aligning the 20-pin
connector of the MAX6651 EV kit with the 20-pin
header of the CMAXQUSB interface board. Gently
press them together.
5) Also connect the 12VDC supply to the MAX6651 EV
kit at the pad labeled FAN SUPPLY (±) (the
MAX6651 ’ s +5V supply comes from the CMAXQUSB
board).
6) Ensure that the jumper settings are in the default
position (Table 1).
7) Connect a 12V tachometer-output fan to the
FAN0+, FAN0-, and FAN0T terminals. Additional
fans may be connected at FAN1+/FAN1-,
FAN2+/FAN2-, and FAN3+/FAN3-. Optional
tachometer inputs FAN1T, FAN2T, and FAN3T may
be used to monitor the auxiliary fans ’ speed.
8) Connect the USB cable from the PC to the CMAX-
QUSB board. A Building Driver Database window
pops up in addition to a New Hardware Found
message. If you do not see a window that is similar
to the one described above after 30 seconds,
remove the USB cable from the CMAXQUSB and
reconnect it. Administrator privileges are required
to install the USB device driver on Windows
98SE/2000/XP. Refer to the TROUBLESHOOT-
ING_USB.PDF document included with the software
if you have any problems during this step.
9) Follow the directions of the Add New Hardware
Wizard to install the USB device driver. Choose the
Search for the best driver for your device option.
Specify the location of the device driver to be
C:\ Program Files\MAX6651 (or the directory cho-
sen during installation) using the Browse button.
10) Turn on the power supply. The fan will turn on at full
speed.
11) Start the MAX6651 program by opening its icon in
the Windows Start menu.
12) Click the Registers panel at the top of the program.
In the Config register, drop down the full-on combo
box and choose closed-loop mode.
13) In the Speed register, type in the value "100."
Adjust this value up or down to choose the target
fan speed. Increasing the Speed value makes the
closed-loop set point a slower fan speed.
14) Observe measured fan speed in the Tach0
tachometer display.
Detailed Description
of Software
The main window (Figure 1) shows a block diagram of
the MAX6651 EV kit, which allows the user to configure
the Fan Mode and Speed . The Registers tab (Figure
2) shows the register values of the MAX6651. Register
bit fields are presented as drop-down combo boxes.
The Speed and Tach0-3 register values are also trans-
lated into the corresponding fan (RPMs).
Detailed Description
of Hardware
U1, the MAX6651, is an intelligent fan controller. MOS-
FET Q1 regulates the fan voltage (measured by the FB
input). In closed-loop mode, adjusting the fan voltage
set point regulates the main fan ’ s tachometer output.
PCB Layout Tips
For best results, keep the Q1 gate drive trace as short
as possible.
See Figure 3, which shows the MAX6651 EV kit
schematic, and refer to the MAX6651 IC data sheet.
