The power management circuit includes a power switch, a current/voltage detector, a current setting unit, and a control unit. The power switch is coupled to a power supply of the computer system. When the power switch is turned on, it supplies an output current and an output voltage of the power supply to an external device. The current/voltage detector detects the magnitudes of the output current and the output voltage. The current setting unit sets a plurality of current thresholds. When the computer system is in a power-saving state and when the output current is greater than a first current threshold and smaller than a second current threshold or the output voltage is smaller than a first voltage threshold and larger than a second voltage threshold, the control unit issues a notification signal to execute a predetermined operation on the power supply."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low power mode operation when charging a device","description":"A power management circuit is provided.
