Ensure that both files the application (“MAX14921 Eval
PCB”ꢀ andꢀ theꢀ DLLꢀ “msvcr100.dll”)ꢀ areꢀ inꢀ theꢀ sameꢀ
folder. Navigate to the folder with the files and select the
“MAX14921 Eval PCB” application. Double-click on it to
run the application. See Figure 2.

If I have the files on a separate drive, do I need to
move these files to my PC? If you have the files on a
USB memory device, there is no need to move them. As
long as the two files remain in the same folder, the applica-
tion runs anywhere, including from a USB memory device.

Detailed Description of Hardware
The MAX14921 EV kit is a fully assembled and tested cir-
cuit board demonstrating the capabilities of the MAX14921
high-accuracy 16-cell battery management AFE IC in an
80-pin surface-mount TQFP package. This EV kit works
withꢀaꢀPC-basedꢀGUIꢀdemonstratingꢀallꢀtheꢀmajorꢀfeaturesꢀ
of the device. The EV kit also features a MAX6126 preci-
sion voltage reference and a MAX11163 16-bit, 500ksps
serial ADC. The MAX14921 and the analog portion of the
ADC are powered by the battery cell stack. All other EV kit
circuits are powered from the USB interface.
Does the application install a driver on my PC? No,
it does not. The application needs no drivers other than
those built into Windows.
Onceꢀtheꢀapplicationꢀisꢀrunning,ꢀyouꢀshouldꢀseeꢀaꢀwindowꢀ
similar to the one in Figure 3. Most of the data items are
blank and are automatically filled in when the application
detects an EV kit attached to any USB port on the computer.
Step 3: Attach the EV Kit to the PC
Ensure that the total cell stack voltage does not
exceed 65V. Reduce the number of cells in the stack,
if needed, to keep to 65V or lower.
Use the USB cable to attach the EV kit to the PC. The
correct USB connector on the EV kit is labeled P102, and
