UBA1702 Line interrupter driver and ringer

UBA1702 Description

INTEGRATED CIRCUITS DATA SHEET UBA1702; UBA1702A Line interrupter driver and ringer Product speciļ¬cation Supersedes data of 1996 Jan 09 File under I.
The UBA1702; UBA1702A performs the high voltage interface and ringer functions of the corded analog telephone set in close cooperation with a microcon.

UBA1702 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; DM

UBA1702 Applications

* Miscellaneous UBA1702; UBA1702A
* Separated ground pins for transmission circuit interface and control signals (e. g. for TEA1064A)
* Possibility to supply the microcontroller with an external voltage source.
* Telephone sets with software controlled ringer function
