LCP22

Protection IC for ringing SLICs

Datasheet − production data

Description

The LCP22 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.

LCP22 can be used to help equipment to meet

various standards such as UL1950, IEC 60950 /

CSAC22.2, UL1459 and TIA-968-A. LCP22

pinout and clearance is compatible with UL60950.

A Trisil ™ meets UL94 V0.

Features

•

Protection IC recommended for ringing SLICs

Wide firing voltage range: -120 V to +120 V

The LCP22 associated with Epcos PTC model

B59173C1130A151 is compliant with

ITU TK20/K21 (4 kV lightning and AC power fault

tests).

Low gate triggering current: I = 5 mA max

Peak pulse current: I = 50 A (10/1000 µs)

Holding current: I = 150 mA min.
