STMicroelectronics LCP12 Protection ICs

STMicroelectronics LCP12 protection ICs for ringing SLICs protect SLICs operating on both negative and positive battery supplies as well as high voltage SLICs. STMicroelectronics LCP12 protection ICs provide 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. These STMicroelectronics protection ICs feature a wide firing voltage range (-120V to +120V) and are ideal for a variety of applications, including dual battery supply voltage SLICs, digital subscriber line access multiplexers, and digital loop carriers.
