Power Management Device, Power Management Method and Portable Electronic Device

摘要

A power management device for a portable electronic device includes a sensing unit, coupled between a power supply and a system circuit of the portable electronic device, for sensing current outputted from the power supply to the system circuit, to generate a sensing signal, and a control unit, coupled between the sensing unit and a charger module of the portable electronic device, for indicating the charger module to stop charging when the sensing signal indicates that current outputted from the power supply to the system circuit is greater than a predetermined value.
