A secondary battery protection circuit includes a first memory circuit electrically connected to a secondary battery, a comparison circuit electrically connected to the first memory circuit, a second memory circuit electrically connected to the comparison circuit, and a power-off switch electrically connected to the second memory circuit. The power-off switch is electrically connected to the secondary battery, and the first memory circuit includes a first transistor including an oxide semiconductor and retains a voltage value of the secondary battery in an analog manner."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secondary battery protection circuit and secondary battery anomaly detection system","description":"Safety is secured in such a manner that an anomaly of a secondary battery is detected with a protection circuit, for example, a phenomenon that lowers the safety of a secondary battery, particularly a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11990778","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.
