LITHIUM-ION BATTERY PROTECTION IC (FOR 3-CELL)
The S-8233A Series is a series of lithium-ion rechargeable
battery protection ICs incorporating high-accuracy voltage
detectors and a delay circuit. This series is suitable for
protecting a three-cell pack.

Without over charge detection / release hysteresis.
When you make the control pin at floating state in upper row above (“Normal”), both charging and discharging are disabled since FETs for
charging and for discharging are turned off.
When you apply Vss potential from outside to the control pin in lower row above (“Inverting”), both charging and discharging are disabled
since FETs for charging and for discharging are turned off.
