Description
The BA20550-24U is an IC chip that contains the necessary functions to build a fully electronic telephone set. The chip is designed to operate at a low DC line voltage, down to 1.45 V (excluding voltage drop over external polarity guard). It provides regulated 3.3 V supply (VDD) for the dialler part and peripherals compatible with speech mode, ringer mode, and trickle mode. It also has an unregulated supply (VCC) for the transmission part and peripherals.
