Application Circuit And Information
1.Typical Tone Ringer
The AC ringing voltage appears across the TIP and RING inputs of the circuit and is
attenuated by capacitor(C
1
) and resistor (R
1
). C
1
also provides isolation from DC
voltages(48V) on the line. After full wave rectification by the bridge, the waveform is
filtered by capacitor(C
4
) to provide a DC supply for Tone Ringer chip. As this voltage
exceeds the initiation voltage V
CC(INI)
oscillation starts. With the components shown, the
output frequency chops between f
H1
and f
H2
at a f
L
rate. The loudspeaker load is coupled
through a 1300
to 8
transformer. To prevent DC power supply regulation problems due
to high source impedance of the telephone line and coupling components C
1
and R
1
, while
the output impedance of the 5001P circuit is quite low, the load impedance must be kept
fairly high. The output coupling capacitor (C
5
) is required with transformer coupled loads.
The variable resistor (R
6
) is used to adjust the audio amplitude and resistor (R
4
) is a
current limiting resistor. Resistor R
5
is a quenching resistor used to limit back emf
generated by the inductive load when ringing stops. When driving a piezo-ceramic
transducer type load, the coupling capacitor (C
5
) is not required. However, a current
limiting resistor is required as is a 29V zener diode in parallel with the transducer. This
diode limits the voltage transients than can be generated by mechanical shocking of piezo-
ceramic transducer.
In the 5002P circuit, the initiation supply current I
CC(INI)
can be changed by using external
resistor(R
SL
). The resistor (R
SL
) is connected to GND from pin2. As this initiation voltage
remains constant independent of R
SL
, the supply initiation current f
CC(INI)
varies inversely
with R
SL
. Thus, increasing the value of R
SL
will decrease the amount of AC ringing current
required to trigger the device. R
SL
can also be used to compensated for smaller AC line
