BATTERY PROTECTION IC FOR SINGLE-CELL PACK
S-8261 Series
(12) Test Condition 12, Test Circuit 2 (Product with 0 V battery charge inhibition function)
〈〈 0 V Battery Charge Inhibition Battery Voltage 〉〉
The 0 V battery charge inhibition battery voltage (V_0INH) is defined as the voltage between VDD and VSS at
which V_CO goes “H” (V_VM + 0.1 V or higher) when the voltage V1 is gradually increased from the starting
condition of V1 = 0 V and V2 = −4 V.
