Product overview
概要
The EVAL-L9963-NDS is a hardware tool for L9963 for Li-ION battery management application. The board is intended to be used as a single node in a distributed BMS. EVAL-L9963-NDS is needed when the total number of battery cells to be managed exceeds 14. The number of nodes to be stacked depends on total battery voltage, additional nodes can be added via additional EVAL-L9963-NDS. A maximum of 14 total nodes beyond the base node EVAL-L9963-MCU or an EVAL-L9963 can be stacked. It has to be used in conjunction with EVAL-L9963-MCU or an EVAL-9963 as second stage or stacked with additional EVAL-L9963-NDS. EVAL-L9963-NDS allows the user to manage up to 14 channels for cell voltage sensing, one channel for current sensing, and up to 4 analog input for temperature sensing (plus an additional on-board NTC to sense PCB temperature). The board provides additional protection for hot plug.
EVAL-L9963-NDS is not intended to be used as a standalone evaluation board but with EVAL-L9963-MCU or EVAL-L9963.
