bq769x0 Family Top 10 Design Considerations

The bq769x0 family of battery monitor devices provides Analog Front End (AFE) and hardware protection functions for 3 to 15 cell lithium-ion battery systems. This document describes 10 design considerations for using the bq769x0 component in a battery circuit. These items should help a designer with decisions which must be made in their implementation of a battery using the bq769x0 family components.
