Description

The CPC7592 is a member of Clare’s next generation Line Card Access Switch family. This monolithic 6-pole solid-state switch is available in either a 16-pin SOIC or a 16-pin DFN package. It provides the necessary functions to replace two 2-Form-C electro-mechanical relays used on traditional analog and contemporary integrated voice and data (IVD) line cards found in Central Office, Access, and PBX equipment. Because this device contains solid state switches for tip and ring line break, ringing injection/return and test access it requires only a +5V supply for operation and logic-level inputs for control.

The CPC7592 is very similar to the Clare CPC7582 with the addition of controlled start-up states and TTL compatible logic inputs.

The CPC7592xC logic provides alternative test states from the CPC7592xA/B and while also providing greater protection SCR trigger and hold current ratings.

Features

• TTL logic level inputs for 3.3V logic interfaces

• Smart logic for power up / hot plug state control

• Small 16-pin SOIC or 16-Pin DFN Package

• DFN package printed-circuit board footprint is 60

percent smaller than the SOIC version, 70 percent

smaller than 4th generation EMR solutions.

• Monolithic IC reliability

• Low matched RON

• Eliminates the need for zero cross switching

• Flexible switch timing to transition from ringing mode

to talk mode.

• Clean, bounce-free switching

• Tertiary protection consisting of integrated current

limiting, voltage clamping, and thermal shutdown for

SLIC protection

• 5 V operation with power consumption < 10 mW

• Intelligent battery monitor

• Latched logic-level inputs, no external drive circuitry

required
