When the value of the power supply voltage becomes a second threshold value or higher which is greater than the first threshold, a second start-up circuit (40) turns on a PMOS transistor (MP3) of a voltage dividing circuit (30), and a second voltage value (VB) output from the voltage dividing circuit (30) becomes a value, which is derived by dividing the value of the power supply voltage according to the resistance ratio of resistors (R31, R32). From a voltage comparison circuit (50), a reset level voltage value is output when the second voltage value (VB) is smaller than the first voltage value (VA), and a power-supply voltage level voltage value is output if the second voltage value (VB) becomes the first voltage value (VA) or higher."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power-on reset circuit","description":"When the value of a power supply voltage (VDD) becomes a first threshold value or higher, a first start-up circuit (20) causes a band gap reference circuit (10) to start a stable operation and a first","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8519755","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.
