BATTERY PROTECTION IC
FOR 3-SERIAL-CELL PACK
S-8233C Series
The S-8233C Series is a series of lithium-ion rechargeable battery
protection ICs incorporating high-accuracy voltage detection circuits and
delay circuits.
The S-8233C series includes the function to measure the status of
battery pack.
It is suitable for a 3-serial-cell lithium-ion battery pack.
