3. 2 Nch open-drain output product in S-8223A/C Series

Set SW4 and SW5 to OFF.

3. 2. 1 Active "H"

Set SW5 to ON after setting V1 = 9.4 V, V2 = V3 = 9.3 V, V5 = 28 V. I2 is the CO pin leakage current

Set SW5 to ON after setting V1 = 5.2 V, V2 = 2.8 V, V3 = 2.5 V, V5 = 0 V. I2 is the CO pin sink current

3. 2. 2 Active "L"

at that time.

Set SW5 to ON after setting V1 = 5.2 V, V2 = 2.8 V, V3 = 2.5 V, V5 = 0 V. I2 is the CO pin sink current

3. 3 S-8223B/D Series

Set SW4 and SW5 to OFF.
