BATTERY PROTECTION IC FOR 3-SERIAL-CELL PACK

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.

Features

(1) Internal high-accuracy voltage detection circuit
• Over charge detection voltage 3.80 ± 0.05 V to 4.40 ± 0.05 V
5 mV - step
• Over charge release voltage 3.45 ± 0.10 V to 4.40 ± 0.10 V
5 mV - step
(The over charge release voltage can be selected within the range where a difference from over
charge detection voltage is 0 to 0.35 V at 50 mV - Step)
• Over discharge detection voltage 2.00 ± 0.08 V to 2.80 ± 0.08 V
