HC-5509A1
SLIC
Subscriber Line Interface Circuit
Description
The HC-5509A1 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 func-
tions of the line card. Together with a secondary protection
diode bridge and 鈥渇eed鈥?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:
鈥?/div>
Battery Feed with Subscriber Loop Current Limiting
鈥?/div>
Overvoltage Protection
鈥?/div>
Ring Relay Driver
鈥?/div>
Supervisory Signaling Functions
鈥?/div>
Hybrid Functions (with External Op-Amp)
鈥?/div>
Test (or Battery Reversal) Relay Driver
鈥?DI Monolithic High Voltage Process
鈥?Compatible with Worldwide PBX and CO Performance
Requirements
鈥?Controlled Supply of Battery Feed Current with Programmable
Current Limit
鈥?Operates with 5V Positive Supply (V
B+
)
鈥?Internal Ring Relay Driver and a Utility Relay Driver
鈥?High Impedance Mode for Subscriber Loop
鈥?High Temperature Alarm Output
鈥?Low Power Consumption During Standby Functions
鈥?Switch Hook, Ground Key, and Ring Trip Detection
鈥?Selective Power Denial to Subscriber
鈥?Voice Path Active During Power Denial
鈥?On Chip Op-Amp for 2 Wire Impedance Matching
Applications
鈥?Solid State Line Interface Circuit for PBX or Central Office
Systems, Digital Loop Carrier Systems
鈥?Hotel/Motel Switching Systems
鈥?Direct Inward Dialing (DID) Trunks
鈥?Voice Messaging PBX鈥檚
鈥?High Voltage 2W/4W, 4W/2W Hybrid

In addition, the SLIC provides selective denial of power to
subscriber loops, a programmable subscriber loop current
limit from 20 to 60mA, a thermal shutdown with an alarm out-
put and line fault protection. Switch hook detection, ring trip
detection and ground key detection functions are also incor-
porated in the SLIC device.
The HC-5509A1 SLIC is ideally suited for line card designs
in PBX and CO systems, replacing traditional transformer
solutions.
