- Subscriber Line Interface Circuit Protector - Data
Data Sheet October 1997 L7591 Subscriber Line Interface Circuit Protector Features s Description The L7591 Subscriber Line Interface Circuit (SLIC) Protector is designed to protect line-feed circuitry from fault-induced lightning and power-cross surge pulses. If a fault current forces TIP and, or RING to a more negative voltage than VS, current is conducted through the trip circuit. When the speci ed trip current level is reached, transistors PNPN1 and, or PNPN2 will turn on and "crowbar" the
