18. Overcharge detection delay time, overcharge release delay time
(Test circuit 5)
The overcharge detection delay time (t_CU) is the time needed for V_CO to go to "L" just after the voltage V1 increases
and exceeds V_CU from the set conditions of V1 = V2 = 3.5 V, V3 = 0 V. After that, the overcharge release delay
time (t_CL) is the time needed for V_CO to go to "H" after the voltage V1 decreases and falls below V_CL.
19. Overcharge alarm detection delay time, overcharge alarm release delay time
(Test circuit 5)
The overcharge alarm detection delay time (t_AU) is the time needed for V_AO to go to "L" just after the voltage V1
increases and exceeds V_CU from the set conditions of V1 = V2 = 3.5 V, V3 = 0 V, V4 = V1 + V2. After that, the
overcharge alarm release delay time (t_AL) is the time needed for V_AO to go to "H" after the voltage V1 decreases
and falls below V_CL before V_CO goes to "L".
20. Overdischarge detection delay time
(Test circuit 5)
The overdischarge detection delay time (t_DL) is the time needed for V_DO to go to "L" after the voltage V1 decreases
and falls below V_DL from the set conditions of V1 = V2 = 3.5 V, V3 = 0 V.
21. Discharge overcurrent 1 detection delay time
(Test circuit 5)
The discharge overcurrent 1 detection delay time (t_DIOV1) is the time needed for V_DO to go to "L" after the voltage V3
increases and exceeds V_DIOV1 from the set conditions of V1 = V2 = 3.5 V, V3 = 0 V.
22. Discharge overcurrent 2 detection delay time
(Test circuit 5)
The discharge overcurrent 2 detection delay time (t_DIOV2) is the time needed for V_DO to go to "L" after the voltage V3
increases and exceeds V_DIOV2 from the set conditions of V1 = V2 = 3.5 V, V3 = 0 V.
23. Load short-circuiting detection delay time
(Test circuit 5)
The load short-circuiting detection delay time (t_SHORT) is the time needed for V_DO to go to "L" after the voltage V3
increases and exceeds V_SHORT from the set conditions of V1 = V2 = 3.5 V, V3 = 0 V.
24. Charge overcurrent detection delay time
(Test circuit 5)
The charge overcurrent detection delay time (t_CIOV) is the time needed for V_CO to go to "L" after the voltage V3
decreases and falls below V_CIOV from the set conditions of V1 = V2 = 3.5 V, V3 = 0 V.
25. 0 V battery charge starting charger voltage (0 V battery charge function "available")
(Test circuit 2)
The 0 V battery charge starting charger voltage (V_0CHA) is defined as the voltage V3 at which V_CO goes to "H" (V_CO
= V_DD) when the voltage V3 is gradually decreased under the set conditions of V1 = V2 = V3 = 0 V.
26. 0 V battery charge inhibition battery voltage (0 V battery charge function "unavailable")
(Test circuit 2)
The 0 V battery charge inhibition battery voltage (V_0INH) is defined as the voltage V1 at which V_CO goes to "L" (V_VM +
0.1 V or lower) when the voltage V1 is gradually decreased from the set conditions of V1 = V2 = 1.5 V, V3 = −6.0 V.
