TISP61060 a.c. ratings. As covered earlier, the gate decoupling capacitor should be 100 nF and should be
mounted as close to the protector as possible.
application circuit
Figure 8 shows a typical TISP61060 SLIC card protection circuit. The incoming line wires, R and T, connect to
the relay matrix via the series over-current protection. Fusible resistors, fuses and positive temperature
coefficient (PTC) resistors can be used for over-current protection. Resistors will reduce the prospective
current from the surge generator for both the TISP61060 and the ring/test protector. The TISP7xxxF3
protector has the same protection voltage for any terminal pair. This protector is used when the ring generator
configuration maybe ground or battery-backed. For dedicated ground-backed ringing generators, the
TISP3xxxF3 gives better protection as its inter-wire protection voltage is twice the wire to ground value.
Relay contacts 3a and 3b connect the line wires to the SLIC via the TISP61060 protector. The protector gate
reference voltage comes from the SLIC negative supply (V
BAT
). A 100 nF gate capacitor sources the high
gate current pulses caused by fast rising impulses.
