DESCRIPTION
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 is
reduced to a safe level until the lower voltage cell is
charged up.
ETA3006 is available in ESOP-8 package.
