Product Summary
The LC4256V75TN100-101 is a protection IC. The LC4256V75TN100-101 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 LC4256V75TN100-101 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 designer to comply with UL1950, IEC950 and CSA C22.2. It is UL 497B approved (file E136224), and has UL94-V0 resin approved.
