This reference design is a high-side, N-channel MOSFET control (up to 32s) battery management unit (BMU), using the stacked BQ769x2 battery monitor family. This design also integrates a CAN interface for BMU stacking high-voltage (up to 1500V) energy storage station applications. 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 48–1500V energy storage systems.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
