ABSTRACT:
A solid state current sensing circuit which is useful in a power supply has bipolar as well as CMOS transistors. The bipolar transistors serve as output transistors and have lateral collectors as well as substrate collectors. The lateral collectors of the bipolar transistors are used to sense a portion of the current carried by the substrate collectors. The lateral collectors are connected to a current mirror which provides an output indication of when the output current exceeds a predetermined amount. The entire circuit can be integrated on a single chip.
