Figure 6. shows the classical protection topology for SLIC using both positive and negative
battery voltages. With such a protection the SLIC is protected against surge over +Vb and
lower than -Vbat. In this case, +Vb can be programmed up to +95 V while -Vbat can be
programmed down to -120 V. Please note that the differential voltage must not exceed
ΔVbat max at 190V.
Figure 7. gives the protection topology for the new SLIC using high negative voltage down to
-120V.
