PRODUCTION DATA
An example circuit layout using the BQ76905 device in a 5-series cell design is described below. The design uses a 2.175-inch × 1.400-inch 2-layer circuit card assembly, with cell connections on the left edge, and pack connections along the bottom edge of the board. Wide trace areas are used, reducing voltage drops on the high current paths.
The board layout, which is shown in Figure 8-9 and Figure 8-10, includes spark gaps with the reference designator prefix E. These spark gaps are fabricated with the board and no component is installed.
