ABSTRACT:
A two-port circuit for passing signal voltages while limiting the current that can flow in either direction. The circuit includes a first pair of bipolar transistors having their emitters directly coupled to a first node and their bases directly coupled to a second node. A resistor that carries the current is connected between the two nodes, in parallel with the base-emitter junctions of the transistor pair. A second transistor pair have their emitters coupled directly to the second node and diodes, oriented in opposite directions, coupled between their collectors and a third node. Each transistor pair includes an npn transistor and a pnp transistor. The current flows through the resistor and one of the transistors of the second pair, depending on the current's direction. A transistor of the first pair can turn on to control a transistor of the second pair to limit the current in either direction.
