In one novel aspect, a method is provided to adaptively control the load switch based on the output condition of a rectified output according to a predefined criteria. In one embodiment of the invention, the methods to adaptively control the load switch comprises a first stage that turns on the load switch quickly; a second stage that stops turning on the load switch and holds the load switch at its current value; a third stage that slowly pulls down the load switch; and a fourth stage that quickly turns off the load switch. In another embodiment, an integrated circuit for a wireless power pick up unit is provided to control the load switch adaptively based on a rectified output feedback and a predefined criteria."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Auto load switch detection for wireless power receiver","description":"Apparatus and methods are provided to automatically detect and control a load switch for a wireless power receiver.
