LCP12 Datasheet (ST Microelectronics) - Protection IC for ringing SLICs

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
