16. Discharge overcurrent detection delay time
(Test circuit 5)
The discharge overcurrent detection delay time (t_DIOV) is the time needed for V_DO to go to "L" after the voltage V2
increases and exceeds V_DIOV under the set conditions of V1 = 3.4 V, V2 = 0 V.
17. 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 V2
increases and exceeds V_SHORT under the set conditions of V1 = 3.4 V, V2 = 0 V.
18. 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 V2
decreases and falls below V_CIOV under the set conditions of V1 = 3.4 V, V2 = 0 V.
19. 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 absolute value of voltage V2 at which V_CO
goes to "H" (V_CO = V_DD) when the voltage V2 is gradually decreased from the starting condition of V1 = V2 = 0 V.
20. 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_CO =
V_VM) when the voltage V1 is gradually decreased, after setting V1 = 1.9 V, V2 = −4.0 V.
