CPC7591

Line Card Access Switch

Features

• TTL logic level inputs for 3.3V logic interfaces

• Smart logic for power up / hot plug state control

• Improved switch dv/dt immunity of 500 V/

μs

• Small 16-pin SOIC or 16-pin DFN package

• DFN package printed-circuit board footprint is 60

percent smaller than the SOIC version, 40 percent

smaller than fourth generation EMR solutions.

• Monolithic IC reliability

• Low, matched R

ON

• Eliminates the need for zero-cross switching

• Flexible switch timing for transition from ringing

mode to idle/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

Applications

• VoIP Gateways

• Central office (CO)

• Digital Loop Carrier (DLC)

• PBX Systems

• Digitally Added Main Line (DAML)

• Hybrid Fiber Coax (HFC)

• Fiber in the Loop (FITL)

• Pair Gain System

• Channel Banks

Description

The CPC7591 is a member of Clare’s next generation

Line Card Access Switch (LCAS) family. This

monolithic 4-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 the

2-Form-C electromechanical ringing relay and it’s

associated snubber circuitry on traditional analog line

cards or contemporary integrated voice and data (IVD)

line cards found in Central Office (CO), Access, and

PBX equipment. Because this device contains solid

state switches for tip and ring line break and for ringing

injection/return, it requires only a +5 V supply for

operation and TTL logic-level inputs for control. The

CPC7591 provides stable start-up conditioning during

system power up and for hot plug insertion

applications. Once active, the inputs respond to

traditional TTL logic levels, enabling the CPC7591 to

be used with 3.3V-only logic.

For negative transient voltage protection the

CPC7591xA versions include SCRs to provide voltage

fold-back protection for the SLIC and subsequent

circuitry, while the CPC7591xB versions utilize

clamping diodes to the VBAT pin. For positive transient

voltage protection all versions provide clamping

diodes to the FGND pin.
