R5650 Series
3-Cell to 5-Cell Li-ion Battery Protection IC with Thermal Protection

Product Specifications

The R5650 is an overcharge and discharge protection IC for 3- to 5- series cell Li-ion / Li-polymer rechargeable battery pack, further includes a short-circuit and protection circuits for charge / discharge overcurrent. The R5650 supports 3 to 5 cells connected in series, forcing a certain voltage on SEL1 and SEL2 pins can select any number of cells.
