DESCRIPTION
The PC-R302 Series Telephone Ring Generators offer a line of high
performance sine wave ring generators with an advanced constant
output power driving stage. The device is internally controlled by a
unique micro-controller, which enables flexibility in setting both the
output frequency in the range of 15 to 50Hz and output amplitude in
the range of 45 to 86Vrms1. The internal controller automatically
adjusts and recovers the output amplitude for overload, overtemperature, and short circuit.
At power connection or start-up by the Inhibit terminal, the device
turns it' output On and Off at the sine wave zero crossing, and
provides an isolated zero crossing synchronization output. The PCR302 Series advanced four-quadrant power topology delivers high
efficiency over the entire input voltage range of 36-72Vdc, and
operates at -40°C to +85°C.
Output Overvoltage Protection
An independent internal protection circuitry shuts down the ring
generator in the event that the output voltage tries to exceed its
defined operating range. This feature allows meeting international
safety standards. The ring generator automatically recovers when the
output voltage returns to its safe operating range. An external
Transient Voltage Suppressor device should be used for external
high voltage transient protection.
Automatic Overload Control
Loads exceeding the maximum rated load by 1% to 20% activate the
Overload Protection. While the Overload Protection is active, the ring
generator automatically reduces its output amplitude and raises its
output current limit in order to sustain output power of approximately
30 Watt. The ring generator gradually reduces its output amplitude
from any set nominal amplitude until it reaches 45Vrms2 for an
unlimited period. For handling overload that requires voltage lower
than 45Vrms, the device reduces its output amplitude to 30Vrms and
remains at this level for duration limited only by the thermal
protection. The device will shut off for a maximum duration of 2
seconds if the output current exceeds approximately 1Arms. While
the output is disabled, the Test output changes to a low logic level.
After a maximum delay of 2 seconds, the ring generator automatically
reverts to normal operation depending on its existing load condition.
This unique procedure ensures continuous service during overload
conditions.
Thermal Protection
An internal thermal protection automatically reduces the ring
generator output power, according to an internally programmed Safe
Operating Area, in the event that the internal temperature exceeds a
preset threshold. The ring generator automatically reverts to full
output power once the internal temperature reduces to the specified
operating temperature range.

Input Under/Over Voltage Protection
The input voltage protection circuitry shuts down the ring generator
when the input voltage is under/over the defined operating range.
The ring generator automatically reverts to normal operation when
the input voltage returns to its defined operating range.
Digital On/Off Control
The Inhibit control terminal (pin 7) functions to shut down the output
and reduces the device current consumption to an idling level. TTL
logic levels referenced to the FGND terminal (pin 6) operate the
Inhibit terminal. When this input is disconnected or tied to a TTL low
level, the output is enabled. A logic high level inhibits the output and
minimizes the device's current consumption to an idling level. Turn
On and Off functions are executed during the output sine wave zero
crossing, improving reliability.
Note that the Inhibit control can be used to generate the ringing
signal's On/Off intervals. Inhibit control eliminates the need for
additional external components in cadence implementation.

LOW PROFILE 30 Watt Sine Wave Telephone Ring Generator
Output Amplitude Setting
The PC-R302-925/926 ring generator output amplitudes may be set
to any value in the range of 45Vrms to 86Vrms. The PC-R302-825
ring generator has an extended output amplitude range of 5095Vrms. The PC-R302-543 ring generator output amplitude is set to
86Vrms.
The V0 input terminal (pin 10) controls the output amplitude in digital
and analog operation modes. When V0 is set to <1V in reference to
the DGND terminal (pin 12), or shorted to DGND, the output
amplitude is set to its default 75Vrms value. When V0 >4V or V0 is
left open, the output voltage is sets to 86Vrms. When applying to V0
voltage in the range of 1.152V to 3.804V the device changes to its
analog amplitude setting mode, and sets its output amplitude
according to the table below. Any output voltage setting will take
effect only at startup, by power connection or by Inhibit command.

Zero Crossing Synchronization Output
The SYNC output terminal (pin 9) provides a square wave at the ring
generators output frequency and phase. The output is an open
collector referenced to the FGND terminal (pin 6). This output may
provide up to 30V signal level by using an external pull up voltage.
This can be used to synchronize relay switching with output's zero
crossing. When the ring generator shuts down as a result of shorted
output, over-temperature or disconnected input voltage, this output
will revert to a high level.
Output Frequency Setting
The PC-R302-925/926/825 ring generator supports all four popular
output frequencies: 17, 20, 25 and 50Hz. The F0 (pin 8) and F1 (pin
11) input terminals select the device output frequency by TTL logic
levels referenced to the DGND terminal (pin 12). Changes take
effect at startup, by power connection or by Inhibit command
activation. The PC-R302-543 ring generator output frequency is set
to 25Hz.

Test Output Signal
The Test output terminal (pin 5), based on an independent internal
circuit, provides an open collector logic high level, referenced to the
FGND terminal (pin 6), to indicate proper functioning of the ring
generator output. A low logic level appears at this terminal when one
of the following occurs: Output Overcurrent, Over Temperature, Vin
Undervoltage/Overvoltage, High Logic Level at the Inhibit Control
Terminal or an Output Overvoltage. While the unit is normally
operated, this output will be at high level. The Test Output Signal can
be used as ‘Output Good Signal’.
