The fail-safe circuit includes a microcomputer that controls the turning on/off of a switch based on an instruction signal from an input terminal, a watchdog circuit that generates a reset signal based on a watchdog pulse from the microcomputer, and a transistor for masking a watchdog pulse for resetting a flip-flop circuit that is set by the reset signal. If a voltage supplied by a power supply circuit is lost, a transistor turns off, and therefore the switch turns on/off according to an instruction signal supplied to an output terminal via a resistor and a diode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fail-safe circuit","description":"A fail-safe circuit enables a switch to turn on/off according to a signal from an external device if a microcomputer that controls the turning on/off of the switch falls into an abnormal state and is ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9748064","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.
