Latest Patents

Kevin Ng holds a patent for a "Current limiting load switch with dynamically generated tracking reference voltage." This invention proposes a current limiting load switch that bridges supply Vss and load with a reference voltage VR dynamically generated by a VR-generator. The design includes a pair of power FET and sense FET interconnected in a split-current configuration. This FET pair develops a load voltage while limiting load current Iload to a preset maximum Imax. The sense FET's high-side terminal is coupled to Vss through a sense resistor Rsense, which develops a sense voltage Vs=Is×Rsense. A current limiting amplifier controls the FET pair, closing a current limiting feedback loop. The VR-generator dynamically adjusts VR concurrent and compensates for undesirable effects caused by the sense FET's operational transition, thus eliminating transitional overshoot of Iload beyond Imax.
