STMicroelectronics EVAL-L9963E-NDS BMS IC Evaluation Board is a hardware tool for L9963E for use in Li-ION battery management applications. The board is intended to be used as a single node in a distributed BMS. EVAL-L9963E-NDS is needed when the total number of battery cells to be managed exceeds 14. The number of nodes to be stacked depends on the total battery voltage. Additional nodes can be added via additional EVAL-L9963E-NDS. A maximum of 31 total nodes beyond the base node EVAL-L9963E-MCU can be stacked. It has to be used in conjunction with EVAL-L9963E-MCU as the second stage or stacked with additional EVAL-L9963E-NDS.
