PRODUCTION DATA
An example circuit layout using the BQ2969 device in a 4-series cell design is described below in Figure 10-1 and Figure 10-2. The design implements the schematic shown in Figure 8-2 and Figure 8-3, and uses a 2-layer circuit card assembly with cell connections on the left edge and pack connections on the right edge of the board.
Care must be taken to place the RC filter components close to the VC pins of the device. Be sure to use a sufficiently wide trace for the NFET source and drain connections to support the maximum current that flows during a fuse blow event.
