摘要： Systems and methods for wireless power transfer systems are described. A controller of a device can detect an overvoltage condition associated with direct current (DC) power being outputted by a rectifier. The controller can, in response to detection of the overvoltage condition, the controller can control a phase of a current of alternating current (AC) power being received by the rectifier to cause the current and a voltage of the AC power to be out of phase.

摘要： In an embodiment, an apparatus is disclosed that comprises a voltage regulator and a regulator booster. The voltage regulator is supplied by an input and is configured to generate a regulated output. The regulated output has a voltage corresponding to an operating point of the voltage regulator. The regulator booster is connected to the voltage regulator and, when activated, is configured to boost the voltage of the regulated output by a target amount. The target amount is at least a portion of a magnitude of a voltage droop relative to the operating point that is caused by a change in a current load on the regulated output.

摘要： An integrated circuit is presented. The integrated circuit includes an internal circuit; a contact pad; and a protective element coupled between the internal circuit and the contact pad. The protective element is operable in a first state or a second state. In the first state the protective element passes a current between the internal circuit and the contact pad. When the current is above a threshold value the protective element changes from the first state to the second state to reduce or prevent the current from flowing between the internal circuit and the contact pad. The protective element may be used to prevent damage to an external circuit connected to the integrated circuit.

摘要： Apparatuses, devices, and methods for operating a multi-level voltage converter are described. A semiconductor device can include a circuit, where the circuit can include a plurality of current sources. The circuit can be configured to measure a flying capacitor voltage across a flying capacitor of a multi-level voltage converter. The circuit can be further configured to compare the flying capacitor voltage with a voltage level equivalent to an intermediate voltage that is between ground and an input voltage being provided to the multi-level voltage converter. The circuit can be further configured to, based on a result of the comparison, switch a current source among the plurality of current sources to maintain the flying capacitor voltage at the intermediate voltage.

摘要： Systems and methods for detecting a plunger movement condition with respect to a solenoid coil are described. A method may include generating a first derivative signal waveform of a current flowing in the solenoid coil, identifying whether there is at least one zero crossing point in the first derivative signal waveform, and detecting the plunger movement condition according to an identification result indicating whether there is at least one zero crossing point in the first derivative signal waveform.

摘要： A circuit and corresponding method for determining a delay are presented. The circuit includes a delay circuit, a feedback circuit and a controller. The delay circuit receives an input signal having an input edge and provides an output signal having an output edge. The input edge and the output edge are separated by a delay. The feedback circuit causes the delay circuit to generate a series of consecutive output pulses. The controller sets the delay to a first delay value and measures a first period of output pulses; sets the delay to a second delay value and measure a second period of output pulses. The controller then calculates the delay based on a difference between the first period and the second period.

摘要： Example implementations include a method of requesting an instruction block associated with one or more instructions and located at one or more addresses of a system memory, obtaining the instruction block from the system memory, generating a hash of the instruction block, obtaining an expected hash associated with the instruction block, comparing the expected hash with the generated hash, in accordance with a determination that the expected hash matches the generated hash, generating a first validation response associated with the instruction block. Example implementations also include a method of obtaining a secure instruction image including an expected hash associated with an instruction block, the instruction block associated with one or more instructions and located at one or more addresses of a system memory, storing the secure instruction image at a configuration register, and enabling the hardware controller to perform one or more hashing operations associated with the instruction block during runtime of a system processor.
