ETA3003 Overview
FEATURES ETA3003 is an inductive cell balancer. Unlike conventional passive balancing technique, ETA3003 utilizes a control scheme with an inductor to shuffle currents between two cells until the cells are balanced. Due to the switching nature, the heat and power dissipation generated in conventional linear balance technique are greatly reduced.
