external mosfet off and on. There are four opration modes as follows:  
1. Overcharge mode:  
The battery voltage of either the H or L cell goes above overcharge detection voltage. The IC shuts down the  
charging loop.Detection operation delay for overcharge detection can be set with the dead time setting pin.  
2. Normal mode  
The battery voltage of both H and L cells is above overdischarge detection voltage and below overcharge  
detection voltage.  
3. Overdischarge mode  
The battery voltage of either the H or L cell drops below overdischarge detection voltage. The IC shuts down  
the discharging loop.Dead time for overdischarge detection is set internally.  
4. Overcurrent mode  
The voltage between CS•GND goes above overcurrent detection voltage during discharge. The IC shuts down  
the discharging loop.
