HC5503PRC

Low Cost SLIC For Large Telecom

Switches

The HC5503PRC 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 and QFN Surface Mount Packaging

• Pb-free Available

Applications

• Central Office, PBX, Call Centers

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which is compatible with both SnPb and

Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed

the Pb-free requirements of IPC/JEDEC J Std-020B.
