BATTERY PROTECTION IC FOR 3-SERIAL- OR 4-SERIAL-CELL PACK
S-8254A Series
9. SEL pin
The S-8254A Series has control pins. The SEL pin is used to switch between 3-cell and 4-cell protection.
When the SEL pin is low, overdischarge detection of the V4 cell is prohibited and an overdischarge is not
detected even if the V4 cell is shorted, therefore, the V4 cell can be used for 3-cell protection. The SEL
pin takes precedence over the battery protection circuit. Use the SEL pin at high or low.
