Undervoltage on V_S
Between V_S(OP) and V_S(UV) the undervoltage mechanism is triggered. If the device is operative and the supply
voltage drops below the undervoltage threshold V_S(UV), the logic switches OFF the channels. As soon as the supply
voltage V_S is above the minimum operative voltage threshold V_S(OP), the channels having either the corresponding
Input pin set to “high” or the OUT.OUTn bit set to “1” are switched ON again (as shown in Figure 12).
