ABSTRACT:
A detection circuit including a first and second sensing circuits detects the presence of load current provided by a utilization circuit to which the detection circuit is coupled to provide an output current that is proportional to the load current. A fraction of the load current that is sourced from the utilization circuit flows through the first sensing circuit the latter of which then provides an output current proportional to the fractional load current. Similarly, a fraction of load current that is sunk by the utilization circuit flows through the second sensing means which provides an output current proportional to the fractional load current.
