BATTERY PROTECTION IC
WITH CELL-BALANCE FUNCTION
Rev.3.4
_00
The S-8209A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and includes a high-accuracy
voltage detection circuit and a delay circuit.
The S-8209A Series has a transmission function and two types of cell-balance function so that users are also able to configure
a protection circuit with series multi-cell.
