Data Sheet October 1997 L7591 Subscriber Line Interface Circuit Protector Features Description s Shunts lightning pulses to ground — Positive or negative 30 A, 10 x 1000 µs — Positive or negative 40 A, 5 x 320 µs — Positive or negative 80 A, 2 x 10 µs s Power-cross protection — 3.5 APEAK, 50 Hz to 60 Hz, 1 s — 5.0 APEAK, 50 Hz to 60 Hz, 10 ms s Gate trigger current, 15 mA max s Up to –80 V capability s Holding current, 150 mA min Pin Information 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.
