Starting condition is V1 = V2 = V3 = V4 = 3.5 V and V
Current that flows between the CTL1 pin and V
The overcharge detection delay time t
after the V1 voltage is rapidly increased from 3.5 V to 4.5 V.
The overdischarge detection delay time t
after the V1 voltage is rapidly decreased from 3.5 V to 1.5 V.
The overcurrent detection delay time 1 is a time needed for the DOP pin voltage to change from “Low” to “High” just after
the VMP pin voltage is decreased from V
Starting condition is V1 = V2 = V3 = V4 = 3.5 V.
Pin voltages of the COP and the DOP should be “High” when V
Pin voltages of the COP and the DOP should be “Low” when V
Pin voltage of the COP is “High” and the pin voltage of the DOP is “Low” when V

One of the 0 V battery charge starting charger voltage and 0 V battery charge inhibition battery voltage is
applied to each product according to the 0V battery charging function.
Starting condition is V1 = V2 = V3 = V4 = 0 V for a product in which 0 V battery charging is available.
The COP pin voltage should be lower than V
Starting condition is V1 = V2 = V3 = V4 = V
The COP pin voltage should be higher than V
