General Description
HC5517B General Description
The HC5517B low cost, 3 REN ringing SLIC is designed to accommodate a wide variety of short loop applications and provides the same degree of flexibility as the high performance HC5517. The flexible features include open circuit tip to ring DC voltages, user defined ringing waveforms, ring trip detection thresholds, and loop current limits that can be tailored for many applications. Additional features of the HC5517B are complex impedance matching, pulse metering, and transhybrid balance. The HC5517B is designed for use in short loop, low cost systems where traditional ring generation is not economically feasible.
The device is manufactured in a high voltage Dielectric Isolation (DI) process. The DI process provides substrate latch up immunity, resulting in a robust system design. A thermal shutdown with an alarm output and line fault protection are also included for operation in harsh environments.
