Embodiments include a current mirror driver circuit that can be coupled to the gates of a VLOFET to form a current mirror that limits current flow through the VLOFET. The current mirror driver circuit provides for pulsed operation so that a coupled VLOFET still toggles between an OFF state and a current limited mode, particularly during a startup period. By using the current mirror driver circuit in conjunction with VLOFETs in circuit pathways that are subjected to startup in-rush current, in-rush current can be regulated to an acceptable level. Notably, no additional impedances are required in circuit pathways that are subjected to startup in-rush current to limit in-rush current, thus avoiding loss of efficiency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Current in-rush limiter","description":"Circuits and methods for limiting excessive current in circuits (such as step-up DC-to-DC converter circuits) in which very low ohmic FETs (VLOFETs) are used in circuit pathways that are subjected to ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11283344","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.
