The charge pump circuit includes a charge pump capacitor. The driving circuit also includes first and second inputs for receiving first and second driving signals from at least one controller, a low-pass filter coupled between the first input and the charge pump circuit to filter the received first driving signal, and a high-pass filter watchdog circuit coupled between the second input and the charge pump circuit to filter the received second driving signal. Example methods of driving a gas valve relay for an HVAC system are also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Safety gas valve relay driving circuits","description":"A safety gas valve relay driving circuit for an HVAC system includes a gas valve relay including an output for selectively enabling and disabling a gas valve in an HVAC system according to an energiza","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10480811","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.
