This reference design is a high-side, N-channel MOSFET control (up to 32s) battery pack, using the stacked BQ769x2 battery monitor family. This design monitors each cell voltage, pack current, cell and MOSFET temperature and protects the battery pack for secure safe use. High-side N-channel MOSFET architecture and optimized driving circuits provide easy switch control. This reference design achieves low stand-by and ship-mode consumption and optimizes the current gaps between two groups. This reference design is for high-cell-count, high-voltage, battery-pack applications.
