HC5503PRI

Low Cost SLIC For Large Telecom

Switches

The HC5503PRI is a low cost SLIC optimized for large

Telecom switches. It combines a flexible voltage feed

architecture with the Intersil latch-free DI bonded wafer

process, to provide a low component count, carrier class

solution at very low cost. The re-configurable design permits

simple, economical solutions for campus-wide call center

and PBX applications. External components can be used in

conjunction with the high battery voltage capability to meet

the complex impedance and long loop drive requirements of

Central Office switches, worldwide.

Features

• Wide Operating Battery Range (-40V to -58V)

• Single Additional +5V Supply

• 30mA Short Loop Current Limit

• Ring Relay Driver

• Switch Hook and Ring Trip Detect

• Low On-Hook Power Consumption

• On-Hook Transmission

• ITU-T Longitudinal Balance Performance

• Loop Power Denial Function

• Thermal Protection

• Supports Tip, Ring or Balanced Ringing Schemes

• Low Profile SO Surface Mount Packaging

• Pb-Free Available (RoHS Compliant)

Applications

• Central Office, PBX, Call Centers
