22. 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 = V5 = 0 V.
23. Charge-discharge inhibition delay time
(Test circuit 5)
23. 1 CTL pin control logic active "H"
Charge-discharge inhibition delay time (t_CTL) is the time needed for V_CO and V_DO to go to "L" after the voltage V5
increases and exceeds V_CTLH under the set conditions of V1 = 3.4 V, V2 = V5 = 0 V.
23. 2 CTL pin control logic active "L"
Charge-discharge inhibition delay time (t_CTL) is the time needed for V_CO and V_DO to go to "L" after the voltage V5
increases and V1 − V5 falls below V_CTLL under the set conditions of V1 = 3.4 V, V2 = V5 = 0 V.
24. 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 = V5 = 0 V.
25. 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 = −2.0 V, V5 = 0 V.
