BATTERY PROTECTION IC FOR 2-SERIAL TO 4-SERIAL-CELL PACK (SECONDARY PROTECTION)
S-8264A/B Series
Operation
1. Overcharge Detection
2. Overcharge Timer Reset
When the voltage of one of the batteries exceeds the overcharge detection voltage (V
conditions and the state is retained for the overcharge detection delay time (t
is called overcharge. Attaching FET to the CO pin provides charge control and a second protection.
In the S-8264A Series, if the voltage of all the batteries decreases below the total of the overcharge detection voltage
(V
longer, CO becomes “L”.
In the S-8264B Series, if the voltage of all the batteries decreases below the total of the overcharge detection voltage
(V
longer, the overcharge status is released; however, CO stays at “H”. When the CTL pin is switched from “L” to “H”, CO
becomes “L”.
