21. Overdischarge detection delay time

(Test circuit 5)

After setting V1 = 3.4 V, V2 = V5 = 0 V, the voltage V1 is decreased. The time interval from when the voltage V1 falls

below VDL until VDO goes to "L" is the overdischarge detection delay time (tDL).

22. Discharge overcurrent 1 detection delay time

(Test circuit 5)

After setting V1 = 3.4 V, V2 = 1.4 V, V5 = 0 V, the voltage V5 is increased. The time interval from when the voltage V5

exceeds VDIOV1 until VDO goes to "L" is the discharge overcurrent 1 detection delay time (tDIOV1).

23. Discharge overcurrent 2 detection delay time

(Test circuit 5)

After setting V1 = 3.4 V, V2 = 1.4 V, V5 = 0 V, the voltage V5 is increased. The time interval from when the voltage V5

exceeds VDIOV2 until VDO goes to "L" is the discharge overcurrent 2 detection delay time (tDIOV2).

24. Load short-circuiting detection delay time

(Test circuit 5)

After setting V1 = 3.4 V, V2 = 1.4 V, V5 = 0 V, the voltage V5 is increased. The time interval from when the voltage V5

exceeds VSHORT until VDO goes to "L" is the load short-circuiting detection delay time (tSHORT).

25. Charge overcurrent detection delay time

(Test circuit 5)

After setting V1 = 3.4 V, V2 = V5 = 0 V, the voltage V5 is decreased. The time interval from when the voltage V5 falls

below VCIOV until VCO goes to "L" is the charge overcurrent detection delay time (tCIOV).

26. 0 V battery charge starting charger voltage (0 V battery charge enabled)

(Test circuit 4)

The 0 V battery charge starting charger voltage (V0CHA) is defined as the absolute value of voltage V2 at which the current

flowing through the CO pin (ICO) exceeds 1.0

μA when the voltage V2 is gradually decreased after setting V1 = V5 =

0 V, V2 = V3 =

−0.5 V.

27. 0 V battery charge inhibition battery voltage (0 V battery charge inhibited)

(Test circuit 2)

The 0 V battery charge inhibition battery voltage (V0INH) is defined as the voltage V1 at which VCO goes to "L" (VCO = VVM)

when the voltage V1 is gradually decreased after setting V1 = 1.8 V, V2 =

−2.0 V, V5 = 0 V.
