General Description

PBL 3796 is an analog Subscriber Line Interface Circuits (SLICs), which are fabricated in a 75 V bipolar, monolithic process.

The programmable battery feed is resistive with short-loop current limiting.

A switch-mode regulator reduces on-chip power dissipation in the active state.

Key Features

  • On-chip switch mode regulator to minimize power dissipation.
  • Programmable, resistive battery feed with short-loop current limiting.
  • Line feed characteristics independent of battery variations.
  • Tip-ring polarity reversal function.
  • Tip and ring open circuit state; tip open with ring active state.
  • Detectors: - programmable loop current detector - ring trip detector.
  • Ring and test relay drivers.
  • Line terminating impedance, comp.
