Test Circuits

1. Overcharge detection voltage, overcharge hysteresis voltage

(Test circuit 1)

pin’s output changes after the voltage of V1 has been gradually increased.

2. Output current

(Test circuit 5)

2. 1 Output current of CMOS output product

Set SW1 and SW2 to OFF.

2. 1. 1 Active "H"

that time.

2. 1. 2 Active "L"

time.

2. 2 Output current of Nch open-drain output product

Set SW1 and SW2 to OFF.

2. 2. 1 Active "H"

Set SW2 to ON after setting V1 = 5.5 V, V2 to V5 = 3.0 V, V7 = 17.5 V. I2 is the CO pin leakage current "L"

2. 2. 2 Active "L"

time.
