※1 0V battery charge function is selected from "Prohibition" or "Permission".
※2 There is occasion as follows of two kinds of release condition from the overcharge status.
a) In the case that the V- pin voltage is lower than the discharging overcurrent detection voltage (Vdet4), EC9526 releases the
overcharge status when the battery voltage falls below the overcharge release voltage(Vrel1).
b) In the case that the V- pin voltage is higher than or equal to the discharging overcurrent detection voltage (Vdet4), EC9526
releases the overcharge status when the battery voltage falls below the overcharge detection voltage (Vdet1).This is a hysteresis
cancellation function.
※3 The release condition from the overdischarge status is that the charger is connected and the V- pin voltage is lower than the
discharging overcurrent detection voltage (Vdet3), and the battery voltage rise more then the overdischarge release voltage(Vrel2).
