ETA3006
DESCRIPTION
FEATURES
ETA3006 is an inductive cell balancer. Unlike conventional passive balancing technique, ETA3006 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. The balance time is also significantly reduced due to higher balancing current not being limited by package thermal dissipation.
ETA3006 consumes only 2µA ultra-low current from batteries in standby mode, extending the battery shelf time. The final balanced voltages of both cells are also highly accurate which enhances the performance and lifetime for the batteries connected in series. ETA3006 can also be used in multiple cells stacking with even number of cells. ETA3006 includes protection features similar to precondition in battery charging, that is when one cell’s voltage is grossly lower than the other, the balancing current...
