  • Interchange circuit overload protection using driver current limiting
    Patent number: 5550700
    Abstract: A low-voltage drop current regulator regulates the current in a data interchange circuit. In one embodiment, the low-voltage drop current regulator couples a positive power supply voltage to the power supply pin of a driver integrated circuit. In another form of the invention, the low-voltage drop current regulator is placed in series with the individual output leads of a driver integrated circuit to couple the respective output signals to respective pins of the data interchange circuit.
