Latest Patents

One of his latest patents is a reference voltage auto-switching mechanism used in regulators for saving more power in low-power mode. This invention provides a circuitry that includes a regulator and a control circuit. The regulator is configured to receive an input signal to generate an output voltage. The control circuit selects one of a first reference voltage and a second reference voltage to serve as an output reference voltage according to the output signal of the regulator. It generates a control signal based on the output reference voltage to control the voltage level of the output voltage of the regulator.

Another significant patent is a charge control circuit, charge control method, and associated power management integrated circuit. This charge control circuit includes an analog to digital converter (ADC) and a control unit. The ADC monitors the temperature of a battery and converts the monitored temperature to a digital value. The control unit determines whether to generate a control signal to adjust a charge current or a charging voltage of a battery based on the digital value. Both the ADC and the control unit are fully hardware architectures.
