BATTERY PROTECTION IC
FOR 2-SERIAL-CELL PACK
S-8262A Series is a protection IC for 2-serial-cell lithium-ion / lithium polymer rechargeable batteries and includes high-
accuracy voltage detectors and delay circuits.
The S-8262A Series has an alarm signal output pin (AO pin) which outputs the alarm detection signal.
The alarm detection signal is output prior to the charge control FET signal by overcharge detection.
