MAX14921 Evaluation Kit
Evaluates: MAX14921
General Description
The MAX14921 evaluation kit (EV kit) demonstrates
a high-accuracy 16-cell battery-management reference
design. The MAX14921 is a high-accuracy 16-cell mea-
surement analog front-end (AFE) in an 80-pin TQFP
surface-mount package. The EV kit features an ADC and
reference, and an isolated interface to a PC through a
USB port to easily measure all cell voltages. Cell stacks
up to 16 cells or 65V can be monitored, whichever is lower.
The EV kit circuit demonstrates all the features of the
device through a GUI application on a Windows^®-based
PC.
