UBA1702 - Line interrupter driver and ringer

General Description

The UBA1702; UBA1702A performs the high voltage interface and ringer functions of the corded analog telephone set in close cooperation with a microcontroller and transmission circuit.

The UBA1702; UBA1702A incorporates several protections, a driver for the line interrupter and a ringer.

Key Features

  • Speech part.
  • Driver for the line interrupter that can be either a PMOST when UBA1702 is used or a PNP when UBA1702A is used.
  • Adjustable over-current protection.
  • Adjustable over-voltage protection for transmission circuit.
  • Adjustable mute (dialling mode voltage; DMO or NSA).
  • Adjustable current loop detection (hook switch status).
  • Microcontroller supply.
  • Provision for electronic hook switch. Ringer part.
  • Over-voltage protectio.
