BATTERY PROTECTION IC FOR 1-CELL PACK
S-8241 Series
(10) Test Condition 10, Test Circuit 1 (Product with 0 V battery charging function)
(0 V battery charge start charger voltage)
Set V1 = V2 = 0 V and decrease V2 gradually. The voltage between VDD and VM at which V_CO goes “H” (V_VM + 0.1 V
or higher) is the 0 V battery charge start charger voltage (V_0CHA).
(11) Test Condition 11, Test Circuit 1 (Product with 0 V battery charge inhibiting function)
(0 V battery charge inhibiting battery voltage)
Set V1 = 0 V and V2 = -4 V. Increase V1 gradually. The voltage between VDD and VSS at which V_CO goes “H” (V_VM +
0.1 V or higher) is the 0 V battery charge inhibiting battery voltage (V_0INH).
