Latest Patents

One of his latest patents is a "Pulse width modulation-based overcurrent protection circuit and operating method for the same." This invention provides a PWM-based overcurrent protection circuit that includes a pulse-width-modulation circuit connected to a charge pump and a load detection circuit. The charge pump outputs a voltage to the power-switch circuit based on a clock-voltage signal. The load detection circuit detects overcurrent flowing through the power-switch circuit, allowing the PWM circuit to control the duty-cycle width of the charge pump to suppress the output voltage, thereby preventing or reducing overcurrent.

Another significant patent is for an "Electronic device having USB power delivery function." This invention includes a connector, an electrostatic discharge (ESD) protection circuit, a power reception notification circuit, and a control circuit. The connector is coupled to a USB host and includes a configuration channel pin. The power reception notification circuit activates a pull-down path of the ESD protection circuit in response to an enable signal. The control circuit manages power reception from the USB host when specific conditions are met.
