Working Principles
BQ24002RGWR operates by regulating the charging current and voltage supplied to the battery. It starts with a constant current mode, where a predetermined current is delivered to the battery until a certain voltage threshold is reached. At this point, it switches to a constant voltage mode, maintaining a steady voltage while reducing the charging current. The charge termination occurs when the current drops below a programmable threshold, indicating that the battery is fully charged.
