APPLICATIONS INFORMATION

protector. The TISP7xxxF3 protector has the same protection voltage for any terminal pair. This protector is used when the ring generator

configuration may be ground or battery-backed. For dedicated ground-backed ringing generators, the TISP3xxxF3 gives better protection as

its inter-conductor protection voltage is twice the conductor to ground value.

Relay contacts 3a and 3b connect the line conductors to the SLIC via the ’61089 protector. The protector gate reference voltage comes from

the SLIC negative supply (V

BAT

). A 220 nF gate capacitor sources the high gate current pulses caused by fast rising impulses.
