The power supply device includes a power transistor, a detection circuit and a driving circuit. The power transistor is controlled by the driving circuit to generate an output current. A first end of the power transistor is coupled to a power voltage pin through a first bonding wire. A second end of the power transistor is configured to output the output current. The detection circuit is coupled between two ends of the first bonding wire to detect the output current and generate a control signal. The driving circuit generates a driving signal according to the control signal. When the output current value is larger than or equal to an over-current-protection current value, the driving circuit starts to adjust a voltage value of the driving signal, such that the output current value is kept at the over-current-protection current value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply device","description":"A power supply device is provided.
