LCP12 Protection IC for ringing SLICs
The LCP12 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 assumed 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
