The overvoltage protection portion (14) also includes: a transistor (P2) operating as a short circuit that short-circuits the source and the gate of the transistor (P1) and that interrupts the input voltage (VIN) when the input voltage (VIN) is in the overvoltage state; a resistor (R2); and a Zener diode (ZD1). The overvoltage protection portion (14) also includes: a transistor (NTr1) operating as a bypass circuit that supplies a constant output voltage (VOUT) from the external terminal (T1) to the internal circuit when the input voltage (VIN) is brought into the overvoltage state; a resistor (R3); and a Zener diode (ZD2)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Overvoltage protection circuit, power supply device, liquid crystal display device, electronic device and television set","description":"An overvoltage protection portion (14) includes a transistor (P1) that achieves continuity with an input voltage (VIN) used as an output voltage (VOUT) to an internal circuit when the input voltage (V","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9632374","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.
