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.

Features & Benefits:

  • Supports worldwide telephony applications as well as non-telephony applications such as instrumentation and industrial controls
  • Minimum external components
  • 3V to 5.5V operation
