Phone Line Supervisory ICs
CPC5712 Phone Line Monitor with Detectors IC
The CPC5712 is a special purpose Phone Line Monitor with
Detectors (PLMD) integrated circuit that is used in various high-
voltage telephony applications such as VoIP gateways and IP-
PBXs. The device monitors the TIP/RING potential through a
high-impedance divider (resistor isolation) to derive two
programmable signal-level detects, polarity information, and a
scaled representation of the phone voltages. In use, the resistor
divider and the high input impedance of the CPC5712 make the
circuit practically undetectable on the line. The high-impedance
resistive barrier application circuit is fully compliant to the
EN60950 safety standard, and meets ITU-T K.21 over-voltage
and over-current specification.

Worldwide Telephony Standards
Mode Input Impedance
The two voltage-level detects are programmed with external
resistors, which gives the designer complete freedom with
respect to line voltage detection levels. The level settings also
have programmable hysteresis to prevent false triggering
conditions. Detection of these levels allows the user to determine
the condition of the line.
This device can also be used in non-telephony applications
such as instrumentation and industrial controls, especially
when a low-level differential level needs to be detected in the
presence of a large common-mode voltage.
