Abstract
This disclosure generally relates to repeaters, and, in particular, repeaters for open-drain systems. In one embodiment, an apparatus comprises a first port, a second port, a current detector, a transistor, and a control logic circuit. A current detector input of the current detector is coupled to the first port. A transistor channel electrode of the transistor is coupled to the second port. A control logic circuit input of the control logic circuit is coupled to the current detector output, and a control logic circuit output of the control logic circuit is coupled to a transistor control electrode of the transistor.
