Abstract: A load switch includes a switch element and first and second control circuits. The switch element has an input terminal for receiving an input voltage, an output terminal for providing an output voltage, and a control terminal for receiving a switch signal, which turns the switch element on and off. The first control circuit is connected to the control terminal of the switch element and turns off the switch element in response to a first control signal. The second control circuit also is connected to the control terminal of the switch element and keeps the switch element turned off, after the first control circuit has turned off the switch element.

Abstract: A surge protection circuit includes a DC trigger circuit that generates a trigger signal when a surge pulse occurs, and a current conducting unit, coupled to the DC trigger circuit, that generates a first clamp voltage as an output voltage of the surge protection circuit and conducts surge currents to ground in response to the trigger signal. The DC trigger circuit includes a surge detection circuit and a first amplification circuit. The surge detection circuit detects if a surge pulse occurs, and triggers the first amplification circuit to generate the trigger signal when the surge detection circuit detects a surge pulse.

Abstract: In an example embodiment, an apparatus includes a bridge rectifier circuit having branches between the AC and DC nodes formed by a set of transistors. A load current measurement circuit includes a current-controlled current source coupled to the bridge rectifier circuit. The current control current source is configured to generate a mirrored current that is a scaled version of a current through at least one of the set of transistors. A current integration circuit is configured to integrate the mirrored current by charging a capacitor with the scaled current in a first mode and discharging the capacitor in a second mode. A sample and hold circuit is configured to set an output node to a voltage equal to a voltage stored by the capacitor in response to the current integration circuit entering the second mode and prior to the discharge of the capacitor.

Abstract: A wireless charging receiver operates on a resonance principle and includes an impedance matching circuit coupled between an antenna and a rectifier circuit. The impedance matching circuit has both series-connected and parallel-connected capacitors. At least one of the capacitors is a tunable variable capacitor. A method is provided for automatically adjusting a capacitance value of the at least one variable capacitor based on an error voltage between a target rectifier voltage and a measured rectifier voltage. Automatically adjusting the antenna impedance of the receiver provides for improved power transfer efficiency for changing operating conditions. In one embodiment, one or more of the parallel-connected capacitors are variable capacitors. In another embodiment, one or more of the series-connected capacitors are variable capacitors.
