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. Because of the practical division of functions between the microcontroll.
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 protection
• Ringer frequency output for frequency discrimination
• Adjustable ringer threshold for piezo-driver enable
• Three bits ringer volume control
• Bridge-tied-load.
