The controller includes an interface circuit, which communicates with the power supply device via the bus line; a processor, which transmits and receives messages to and from the power receiving device by using the interface circuit, determines a voltage level of the bus voltage, and sets the determined voltage level to the power supply circuit; and a watchdog timer, which is cleared whenever the processor executes a ping-related command for transmission or reception of ping messages to or from the power receiving device, wherein an overflow period of the watchdog timer is set to be longer than a period for the ping messages."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Clearing a watchdog timer every time a processor instructs a transmission of a ping message to a power receiving device","description":"A controller, which is installed on a power supply device complying with the USB (Universal Serial Bus)-PD (power delivery) specification and controls a power supply circuit for supplying a bus voltag","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9690641","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
