  • Integrated circuit charge pump with failure protection
    Patent number: 9819260
    Abstract: Disclosed is a charge pump protection device including a power supply voltage, a charge pump to produce an output voltage higher than the power supply voltage, the charge pump including, a pumping capacitor to store voltage during a charging state and to discharge the voltage during a pumping state thereof, a plurality of switches to regulate the charging and pumping states, a charge pump capacitor to store the output voltage, and at least one current limiter in series with at least one of the plurality of switches to limit current and prevent an electrical failure of the charge pump.
    Type: Grant
    Filed: January 15, 2015

  • Dual bridge amplifier configuration
    Patent number: 9385670
    Abstract: An amplifier has a dual bridge design with two bridge amplifiers. A mode switch enables them to be configured in a series amplification mode. The switching of the mode switch is dynamic and enables re-use of signal current thereby improving overall system efficiency. A delay to the mode switch closure is provided in the event of clipping of one of the amplifier outputs. This prevents large cross currents from flowing.

  • Dynamic switchable mode dual bridge power amplifier
    Patent number: 8330539
    Abstract: A dual bridge amplifier includes a first bridge amplifier receiving a first input signal and having a pair of drive outputs connecting to a first load, a second bridge amplifier receiving a second input signal and having a pair of drive outputs connecting to a second load, and a mode switch between one of the drive outputs of the first bridge amplifier and one of the drive outputs of the second bridge amplifier. The mode switch closes and switches the dual bridge amplifier to a series amplification mode, based on detecting the magnitudes of the first and second input signals. The series amplification mode shares current between the first load and the second load, reducing amplifier heat generation.
