DESCRIPTION
The MP2642 is a highly integrated, bidirectional active balancer that provides up to 1A of charge redistribution among Li-ion, Li-polymer, or lithium iron phosphate batteries in a two-series battery pack. As an alternative to dissipating energy with passive balancing, the MP2642 efficiently moves charge between cells to minimize balancing time and heat generation. The device can also compensate for cell capacity mismatch to extend battery runtime.
By combining multiple MP2642 devices, active balancing can be scaled to any number of series cells, and charge can be redistributed to and from any cells within the pack.
The MP2642 can balance adjacent cells using two modes: buck-balance mode and boostbalance mode.
