overcharge detection voltage (VDET1) + 0.2V in the condition V2=0V.

The over-discharge detection delay time (tVDET2 ) is the time needed for VDO to change from "H" to "L"

just after the V1 rapid decrease within 10us from the over -discharge detection voltage (VDET2) + 0.2V to

the over-discharge detection voltage (VDET2) - 0.2V in the condition V2=0V.

(10) Measurement Condition 10, Measurement Circuit 5

(Over-current 1 detection delay time, Over-current 2 detection delay time, Load short-circuiting

detection delay time, Abnormal charge current detection delay time )

Set V1=3.5V and V2=0V. Increase V2 from 0 V to 0.35 V momentarily (within 10 us) The time needed for

VDO to go “L” is over-current 1 detection delay time (tVDET3).

Set V1=3.5V and V2=0V. Increase V2 from 0 V to 0.7 V momentarily (within 10us) The time needed for

VDO to go “L” is over-current 2 detection delay time (tVDET4).

Set V1=3.5V and V2=0V. Increase V2 from 0 V to 1.6 V momentarily (within 10 us) The time needed for

VDO to go “L” is the load short-circuiting detection delay time (tSHORT ).

Set V1=3.5V and V2=0V. Decrease V2 from 0 V to -1.1 V momentarily (within 10 us) The time needed for

VCO to go “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.

(11) Measurement Condition 11, Measurement Circuit 2 (Product with 0V battery charge function)

(0V battery charge starting charger voltage )

Set V1=V2=0V and decrease V2 gradually. The voltage between VDD and V- when VCO goes “H” (V- +

0.1 V or higher) is the 0V battery charge starting charger voltage (V0CHA ).

(12) Measurement Condition 12, Measurement Circuit 2 (Product with 0V battery charge inhibition

function)

(0V battery charge inhibition battery voltage)

Set V1=0V and V2=-4V. Increase V1 gradually. The voltage between VDD and VSS when VCO

goes “H”(V- + 0.1 V or higher) is the 0V battery charge inhibition battery voltage (V0INH ).
