HC-5509B
ITU CO/Loop Carrier SLIC
The HC-5509B telephone Subscriber Line Interface Circuit
integrates most of the BORSCHT functions on a monolithic
IC. The device is manufactured in a Dielectric Isolation (DI)
process and is designed for use as a high voltage interface
between the traditional telephone subscriber pair (Tip and
Ring) and the low voltage filtering and coding/decoding
functions of the line card. Together with a secondary
protection diode bridge and “feed” resistors, the device will
withstand 1000V lightning induced surges, in plastic
packages. The SLIC also maintains specified transmission
performance in the presence of externally induced
longitudinal currents. The BORSCHT functions that the SLIC
provides are:
Battery Feed with Subscriber Loop Current Limiting
Overvoltage Protection
Ring Relay Driver
Supervisory Signaling Functions
Hybrid Functions (with External Op Amp)
Test (or Battery Reversal) Relay Driver
In addition, the SLIC provides selective denial of power to
subscriber loops, a programmable subscriber loop current
limit from 20mA to 60mA, a thermal shutdown with an alarm
output and line fault protection. Switch hook detection, ring
trip detection and ground key detection functions are also
incorporated in the SLIC device.
The HC-5509B SLIC is ideally suited for line card designs in
PBX and CO systems, replacing traditional transformer
solutions.
