Patent number: 11650644Abstract: A Universal Serial Bus (USB) Type-C and power delivery port with scalable power architecture is disclosed. In one aspect, at least two circuits for a USB port are consolidated into a single integrated circuit (IC). At least one of the at least two circuits is part of a Type-C port controller (TCPC) group of circuits including sensors associated with detecting whether a voltage and current are present at pins of a USB receptacle. At least the other one of the at least two circuits is selected from a battery-related group of circuits including a battery charging circuit, an over-voltage protection circuit, and a conditioning circuit. The more circuitry integrated into the single IC the more readily scalable the end product is for a multi-port device. Additional circuitry such as a light emitting diode (LED) driver may also be included in the single IC.Type: GrantFiled: August 18, 2021Date of Patent: May 16, 2023Assignee: QUALCOMM IncorporatedInventors: Christian Gregory Sporck, Georgios Konstantinos Paparrizos, Chunping Song

Patent number: 10489324Abstract: Systems and methods for port management are disclosed. In one aspect, the system may consolidate port management functions as well as power conversion, protection features, and signal conditioning circuitry into a single integrated circuit (IC) for a device without a battery. Further exemplary aspects allow for arbitration between ports to handle power supply versus power sink functions. Still further exemplary aspects provide an indication when a weak power source is coupled to the computing device to alert a user that the weak power source may not provide sufficient power for full operation. Such consolidated functionality allows a single form factor to be used for all ports whether the ports are used as a power port or an output port. Further, such consolidated functionality helps mitigate possible damage caused by improper activity.Type: GrantFiled: August 25, 2017Date of Patent: November 26, 2019Assignee: Qualcomm IncorporatedInventors: Christian Gregory Sporck, Georgios Konstantinos Paparrizos

Publication number: 20180074564Abstract: A first portable or non-portable device enters an adaptive charging mode to deliver a programmable output voltage to a second (e.g., sink) device, independent of a connector between the devices. The adaptive charging mode enables a sink device to detect current and voltage capability of the portable or non-portable device. It is determined whether a first device coupled to the second device through a reconfigurable port is configured as a source device or sink device. A current limit of the source device is then detected. A programmable voltage from the source device is requested based on the detecting.Type: ApplicationFiled: October 6, 2016Publication date: March 15, 2018Inventors: Georgios Konstantinos PAPARRIZOS, Varaprasad ARIKATLA, Giuseppe PINTO, Christian SPORCK

Patent number: 8981733Abstract: In one embodiment the present invention includes a system and method of charging a battery using a switching regulator. In one embodiment, a switching regulator receives an input voltage and input current. The output of the switching regulator is coupled to a battery to be charged. The switching regulator provides a current into the battery that is larger than the current into the switching regulator. As the voltage on the battery increases, the current provided by the switching regulator is reduced. The present invention may be implemented using either analog or digital techniques for reducing the current into the battery as the battery voltage increases.Type: GrantFiled: May 22, 2013Date of Patent: March 17, 2015Assignee: QUALCOMM IncorporatedInventors: M Abid Hussain, Kenneth C Adkins, Georgios Konstantinos Paparrizos
