Description

The LCP02-150B1 has been developed to protect

SLICs operating on both negative and positive

battery supplies, as well as high voltage SLICs. It

provides crowbar mode protection for both TIP

and RING lines. The surge suppression is

managed for each wire by two thyristor structures,

one dedicated to positive surges the second one

for negative surges. Both positive and negative

threshold levels are programmable by two gates

(Gn and Gp). The use of transistors decreases

the battery currents during surge suppression.

LCP02-150B1 can be used to help equipment to

meet various standards such as UL1950,

IEC 60950 / CSAC22.2, UL1459 and TIA-968-A

(formerly FCC part68). A Trisil™ meets UL94 V0

(Trisils are UL497B approved - file: E136224).

LCP02-150B1 Technical information The series resistors Rs1 and Rs2 designed in Figure 7 represent the fuse resistors or the PTCs which are needed to withstand the power contact or the power induction tests imposed by the country standards. Taking this factor into account, the actual lightning surge current flowing through the LCP02-150B1 is equal to: I surge = Vsurge / (Rg + Rs) With V surge = peak surge voltage imposed by the standard.
