Evaluation Kit for the MAX14921

Please check latest availability status for a specific part variant.


The MAX14921 evaluation kit (EV kit) demonstrates a high-accuracy 16-cell battery-management reference design. The MAX14921 is a high-accuracy 16-cell measurement 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.
