Features

Description

• CPC5712 Outputs:

• Two Independent Programmable Level Detectors

with Programmable Hysteresis

• Fixed-Level Polarity Detector with Hysteresis

• Differential Linear Output

• Minimum External Components

• Excellent Common-Mode Rejection Ratio

(CMRR) > 55dB

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.

• Application circuits meet isolation requirements of

worldwide telephony standards

• Worldwide telephone network compatibility

• Single Supply Operation, 3.0V to 5.5V

• High differential input impedance

• Very low common-mode input impedance

• Fixed Gain

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.

• TTL Compatible CMOS Logic Level outputs

• Small SOP 16-Pin package

Applications

• VoIP Gateways, IP-PBX, xDSL

• TIP/RING Monitoring

• Line-In-Use Detection

• Polarity Detection for Caller ID, Enhanced 911

• Battery Detection, PSTN Check

• Non-telephony voltage level detection applications

• Instrumentation

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.
