BATTERY PROTECTION IC FOR 3-SERIAl-CELL PACK
S-8233B Series
Caution At the Measurement circuit from 1 to 10.
If the device’s CTL logic is “normal” (S-8233BA, S-8233BC, S-8233BE) then set the CTL
voltage at VSS (V4=0 V).
If the device’s CTL logic is “reverse” (S-8233BB, S-8233BD) then set the CTL voltage at
VCC (V4=V1+V2+V3).
