LCP02-150B1

® LCP02-150B1 PROTECTION IC FOR RINGING SLICS A.S.D.™ FEATURES s s s s s s Protection IC recommended for ringing SLICs. Wide firing voltage range: from -110V to +95V. Low gate triggering current: IG = 5mA max. Peak pulse current: IPP = 30A (10/1000µs) . Holding current: IH = 150mA min. UL497B approved (file E136224) SO-8 WIDE MAIN APPLICATIONS s s s s s s s s s s Dual battery supply voltage SLICs - negative battery supply configuration - negative & positive battery supply configuration Central Office (CO) Private Branch Exchange (PBX) Digital Loop Carrier (DLC) Asymmetrical Digital Subscriber Line (ADSL G.Lite) Fiber in the Loop (FITL) Wireless Local Loop (WLL) Hybrid Fiber Coax (HFC) ISDN Terminal Adapter Cable modem FUNCTIONAL DIAGRAM TIP Gn Gp GND DESCRIPTION The LCP02-150B1 has been developed to protect SLICs operating on both negative and positive battery supplies, as well as on 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. The LCP02-150B1 has high Bellcore Core, ITU-T and FCC Part 68 lightning surge ratings, ensuring rugged performance in the field. In addition, it is also specified to assist a design...
