BATTERY PROTECTION IC FOR 2-SERIAL / 3-SERIAL CELL PACK (SECONDARY PROTECTION)
Rev.1.2_01
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.
Features
High-accuracy voltage detection circuit for each cell
Overcharge detection voltage n (n = 1 to 3)
3.600 V to 4.
