Description
The LCP02-150M has been developed to protect SLICs operating on both negative and positive supplies, as well as on high voltage SLICs. It provides crowbar mode protection for both TIP and RING lines. Surge suppression is assumed for each wire by two thyristor structures, one dedicated to positive surges, the second one to 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.

Features
