6. Overcurrent 1 detection delay time
(Test condition 5, test circuit 5)
6. 1 V_DIOV2 = 0.1 V
The overcurrent 1 detection delay time (t_DIOV1) is the time period from when the voltage V2 exceeds V_DIOV1 to when
V_DO goes to "L", after V2 is increased to 0.08 V instantaneously (within 10 μs) under the set conditions of V1 =
3.5 V, V2 = 0 V.
6. 2 V_DIOV2 ≥ 0.2 V
The overcurrent 1 detection delay time (t_DIOV1) is the time period from when the voltage V2 exceeds V_DIOV1 to when
V_DO goes to "L", after V2 is increased to V_DIOV1 max. + 0.01 V instantaneously (within 10 μs) under the set
conditions of V1 = 3.5 V, V2 = 0 V.
7. Overcurrent 2 detection delay time, UVLO detection delay time
(Test condition 5, test circuit 5)
The overcurrent 2 detection delay time (t_DIOV2) is the time period from when the voltage V2 exceeds V_DIOV2 to when
V_DO goes to "L", after V2 is increased to 0.9 V instantaneously (within 10 μs) under the set conditions of V1 = 3.5 V,
V2 = 0 V.
The UVLO detection delay time (t_UVLO) is the time period from when the voltage V1 falls below V_UVLO to when V_DO
goes to "L", after V1 is decreased to 1.8 V instantaneously (within 10 μs) under the set conditions of V1 = 3.5 V, V2 =
0 V.
8. Overcurrent 3 detection delay time (Overcurrent 3 detection function "available")
(Test condition 5, test circuit 5)
The overcurrent 3 detection delay time (t_DIOV3) is the time period from when the voltage V2 exceeds V_DIOV3 to when
V_DO goes to "L", after V2 is increased to 1.6 V instantaneously (within 10 μs) under the set conditions of V1 = 3.5 V,
V2 = 0 V.
