Abstract:
1. A high side switch circuit comprising; an input terminal for receiving a current supplied from a power supply; an output terminal for supplying said current to a load; a first switch electrically connected between said input terminal and said output terminal; a resistive element including a first terminal electrically connected to said input terminal and a second terminal electrically connected to said output terminal; and a sensor circuit receiving a detection voltage generated at said resistive element as said current flows between said input terminal and said output terminal, for sensing that said current is an over-current, when said current reaches an over-current level and said detection voltage exceeds a threshold voltage, said sensor circuit including: wherein the adjustment circuit is configured to adjust offset of an input voltage of said comparator, for adjusting said detection voltage, wherein said comparator includes: wherein said adjustment circuit includes a fuse resistor connected to a corresponding one of said plurality of transistors.
