The current detection circuit includes a current sampling circuit and a current comparator circuit. The current sampling circuit provides a first current that is proportional to the total current, a second current that is proportional to the feedback current, and a third current that is proportional to the load current. The current comparator circuit is configured to compare the third current with a threshold current, and output a detection signal that indicates whether the third current matches the threshold current, thereby indicating a target load device is detected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio microphone detection using auto-tracking current comparator","description":"An integrated circuit includes a current detection circuit configured for coupling to an output terminal of a voltage regulator, the output terminal providing a total current that is divided into a lo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11281248","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.
