3 to 5 Serial Cell Li-Ion / Li-Polymer Battery Protection IC with Temperature Protection
The R5651 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 R5651 Cell Li-Ion / Li-Polymer Battery Protection IC can select any number of cells by applying a certain voltage on the SEL pin.
Key Benefits
• Using a current-sense resistor with low resistance ratings: reduction in high temperature in large current and realizing a thermal design of a board easily.
• Separation between charging and discharging paths: achieving low impedance of the battery pack.
• Cascading: achieving simple circuit configuration for battery pack with six-cell and more and reducing external components.
