(9) Measurement Condition 9, Measurement Circuit 1
Overcurrent 1 detection delay time, Overcurrent 2 detection delay time, Load short-circuiting detection delay
time, Abnormal charge current detection delay time
Set V1=3.5V and V2=0V under normal condition. Increase V2 from 0 V to 0.35 V momentarily (within
10
s). The time after V2 becomes overcurrent 1 detection voltage (VIOV1) until VDO goes "L" is overcurrent
1 detection delay time (tIOV1).
Set V1=3.5 V and V2=0 V under normal condition. Increase V2 from 0 V to 0.7 V momentarily (within
1
s). The time after V2 becomes overcurrent 1 detection voltage (VIOV1) until VDO goes "L" is overcurrent 2
detection delay time (tIOV2).
Note: The overcurrent 2 detection delay time starts when the overcurrent 1 is detected, since the delay circuit is
common.
Set V1=3.5 V and V2=0 V under normal condition. Increase V2 from 0 V to 3.0 V momentarily (within
1
s). The time after V2 becomes the load short-circuiting detection voltage (VSHORT) until VDO goes "L" is
the load short-circuiting detection delay time (tSHORT).
Set V1=3.5 V and V2=0 V under normal condition. Decrease V2 from 0 V to -2.5 V momentarily (within
10
s). The time after V2 becomes the charger detection voltage (VCHA) until VCO goes "L" is the abnormal
charge current detection delay time. The abnormal charge current detection delay time has the same value
as the overcharge detection delay time.
(10) Measurement Condition 10, Measurement Circuit 1 (Product with 0V battery charging function)
0V battery charge start charger voltage
Set V1=V2=0 V and decrease V2 gradually. The voltage between VDD and VM at which VCO goes
″H″ (VVM
+ 0.1 V or higher) is the 0 V battery charge start charger voltage (V0CHA).
(11) Measurement Condition 11, Measurement Circuit 1 (Product with 0V battery charge inhibiting function)
0V battery charge inhibiting battery voltage
Set V1=0 V and V2=-4 V. Increase V1 gradually. The voltage between VDD and VSS at which VCO goes
″H″ (VVM + 0.1 V or higher) is the 0V battery charge inhibiting battery voltage (V0INH).
