HC55171 General Description
The HC55171 is backward compatible to the HC5517 with the added capability of driving 5 REN loads. The HC55171 is ideal for any modem or remote networking access application that requires plain old telephone service POTS, capability. The linear amplifier design allows a choice of Sinusoidal, Square wave or Trapezoidal ringing. The voltage feed architecture eliminates the need for a high current gain node achieving improved system noise immunity, an advantage in highly integrated systems.
The device is manufactured in a high voltage Dielectric Isolation (DI) process with an operating voltage range from -16V, for off-hook operation and -80V for ring signal injection.
The DI process provides substrate latch up immunity, resulting in a robust system design.

HC55171B General Description
The HC55171B low cost, 5 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 HC55171. 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 HC55171B are complex impedance matching, pulse metering, and transhybrid balance. The HC55171B 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.
