    Cell Balancing with the bq77PL900
    The bq77PL900 five to ten series cell lithium-ion or lithium-polymer battery protection and AFE IC includes a cell-balancing function. This document describes how to use the cell-balancing feature of the part in a battery pack application. Boosting the current capability of the IC using external FETs is described. The algorithm for balancing in stand-alone mode is described as well as considera
