Power delivery controller integrated circuit for usb apparatus
The patent US12055963B1 describes a power delivery controller integrated circuit designed to manage voltage levels in a universal serial bus (USB) connector configuration channel. The circuit includes a configuration channel pad, two switches, a power delivery controller circuit, and a high voltage sensing circuit. The high voltage sensing circuit monitors the voltage at the configuration channel pad to determine if it exceeds a specified rated range. If the voltage is within the acceptable range, the switch control circuit activates both switches, allowing the power delivery controller to connect to the USB configuration channel. Conversely, if the voltage exceeds the rated range, the switches are turned off, and the circuit maintains a reduced voltage level to protect the components.
Further details of the circuit include various configurations for the high voltage sensing circuit, which can utilize resistor strings, Zener diodes, and additional resistors to generate a divided voltage as a sensing result. The switch control circuit is designed to respond dynamically to the sensing results, ensuring that the first and second switches are activated or deactivated based on the voltage conditions. This integrated approach aims to enhance the reliability and safety of power delivery in USB applications by preventing damage from overvoltage conditions while maintaining operational efficiency.
