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 HC4P5509A1R3060 SLIC is ideally suited for line card
designs in PBX and CO systems, replacing traditional
transformer solutions.
