IVISION

Features

Description

• 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/s

• Monolithic IC Reliability

The CPC7591 is a member of IXYS Integrated

Circuits Division’s next generation Line Card Access

Switch (LCAS) family. This monolithic 4-pole solid

state switch is available in a 16-pin SOIC 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

• Low, Matched R

• 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

• 5V Operation with Power Consumption < 10 mW

• Intelligent Battery Monitor

• Latched Logic-Level Inputs, no External Drive

Circuitry

• Small 16-pin SOIC

applications. Once active, the inputs respond to

traditional TTL logic levels, enabling the CPC7591 to

be used with 3.3V-only logic.

Applications

For negative transient voltage protection the

CPC7591BA version includes SCRs to provide

voltage fold-back protection for the SLIC and

subsequent circuitry, while the CPC7591BB version

• 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

utilizes clamping diodes to the V

pin. For positive

BAT

transient voltage protection all versions provide

clamping diodes to the F

pin.
