Description
The UBA1702T is an electronic component model that falls under the product category of IC Chips. It is designed to perform the high voltage interface and ringer functions of a corded analog telephone set in cooperation with a microcontroller and transmission circuit.
Specifications and features
Speech part:
- Driver for the line interrupter (PMOST for UBA1702, PNP for UBA1702A)
- 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 (BTL) output stage for piezo transducer
- Fast start-up microcontroller supply
Application Scenarios
The UBA1702T can be used in corded analog telephone sets to facilitate high voltage interface and ringer functions. It is suitable for applications that require adjustable over-current and over-voltage protection, adjustable mute and current loop detection. The provision for electronic hook switch and bridge-tied-load (BTL) output stage makes it versatile in different scenarios.
