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.
1. Line Interrupter Driver:
A Line Interrupter Driver, often referred to as a “line interrupter,” is a device used to create a break in the electrical circuit of a telephone line. This break is essential for signaling purposes in some telephony applications, particularly in older analog telecommunication systems. When activated, the line interrupter temporarily disconnects the telephone line, allowing for specific signaling patterns to be transmitted.
Features
1. Driver for the line interrupter that can be either a PMOST when UBA1702 is used or a PNP when UBA1702A is used
2. Adjustable over-current protection
3. Adjustable over-voltage protection for transmission circuit
4. Adjustable mute (dialling mode voltage; DMO or NSA)
5. Adjustable current loop detection (hook switch status)
Pinouts:
Applications:
1. Telephone sets with software controlled ringer function
2. Telephone sets with electronic hook switch.
