CPC5712 Datasheet Voltage Monitor

Manufacturer: IXYS (now Littelfuse)

Overview: INTEGRATED CIRCUITS DIVISION CPC5712 Voltage Monitor with Detectors.

General Description

The CPC5712 is a special purpose Voltage Monitor with Detectors 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 line voltages.

In use, the resistor divider and the high input impedance of the CPC5712 make the circuit practically undetectable on the line.
