The S-8223A/B/C/D Series is used for secondary protection of lithium-ion rechargeable batteries, and incorporates high-accuracy
voltage detection circuits and delay circuits.
Short-circuits between cells accommodate series connection of two cells or three cells.
The S-8223B/D Series limits its CO pin output
voltage to 11.
5 V max.
, so a FET with the gate withstand
voltage of 12 V can be used.
