BATTERY PROTECTION IC FOR 2-SERIAL-CELL PACK
S-8242B Series
12. 0 V Charge Inhibition Battery Voltage (Products in Which 0 V Charge Is Unavailable)
(Test Condition 12, Test Circuit 2)
The 0 V charge inhibition charger voltage (V0INH) is defined as the voltage between the VDD pin and VSS pin at which
VCO goes to “H” (VVM + 0.1 V or higher) when the voltages V1 and V2 are gradually increased from the starting
condition of V1 = V2 = 0 V, V3 = −4 V.
