Low Cost SLIC For Large Telecom
Switches
Features
• Wide Operating Battery Range (-40V to -58V)
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.

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and 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-020C.
