The power management circuit further has a current limiting circuit, an over-current indication circuit and an over-current threshold selecting circuit. The current limiting circuit compares a current feedback signal indicative of an output current flowing out of the power terminal with a current threshold signal and generates a square wave signal. The over-current indication circuit generates an over-current indication signal based on the square wave signal. The over-current threshold selecting circuit selects a first over-current threshold voltage or a second over-current threshold voltage as an over-current threshold voltage based on the over-current indication signal, wherein the first over-current threshold voltage is higher than the second over-current threshold voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power management circuit with over-current protection and over-current protection method thereof","description":"A power management circuit has a power input terminal coupled to a power supply or a load, a power terminal configured to provide an output voltage, and a battery terminal coupled to a battery.
