17. Discharge overcurrent detection delay time
(Test circuit 5)
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.
18. Load short-circuiting detection delay time
(Test circuit 5)
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.
19. Charge overcurrent detection delay time
(Test circuit 5)
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.
20. 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 absolute value of the voltage V2 at which V_CO
goes to "H" (V_CO = V_DD) when the voltage V2 is gradually decreased under the set condition of V1 = V2 = 0 V.
21. 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 "H" (V_CO
= V_DD) when the voltage V1 is gradually increased under the set conditions of V1 = 0 V, V2 = −2.0 V.
