LCP02-150B1
The LCP02-150B1 topology is particularly optimized for the new telecom applications such as fiber in the
loop, WLL systems, decentralized central office for example. The schematics of figures 6 and 7 give the 2
most frequent topologies used for these emergent applications

Figure 6 shows the classical protection topology for SLIC using both positive and negative battery volt-
ages. 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 +95V while -Vbat can be programmed down to -110V. Please note
that the differential voltage does not exceed Vbat max at 190V.
Figure 7 gives the protection topology for the new SLIC using high negative voltage down to -110V.
