GS7702
General Description
The GS7702 is a cell balance controlled IC that can manage 1 % voltage difference in two Li-ion cells when Li-ion battery during operation. Internal switches and an external resistor is across the two Li-ion cells, when one of internal switches is turn on, the maximum current (balancing current) that can be drawn from or bypassed from the cell is 200mA.
