Power management device and power management method

Abstract

The invention provides a power source management device and a power source management method. The power source management device comprises an externally-connected circuit, a processing unit, a current detection circuit and a judging module, the externally-connected circuit is used for being connected to an externally-connected device and supplying an externally-connected power source to the same through a power source, the processing unit is used for enabling the power source management device to enter a sleeping state when the power source management device meets a preset condition, the current detection circuit is used for detecting first supply current generated by the power source under the sleeping state when the externally-connected power source is supplied to the externally-connected device, the judging module is used for generating a judging value according to the first supply current and comparing the judging value with a preset current value to generate a judging result, and the judging result is used for judging whether power consumption of the externally-connected device is normal or not. The power source management device and the power source management method can be used for detecting whether the power consumption of the externally-connected device is normal or not.

Description

technical field

[0001] The present invention relates to a power management device and a power management method, in particular to a power management device and a power management method capable of judging whether the power of an external device is abnormal. Background technique

[0002] In recent years, electronic devices have become more and more common and have more and more functions. For example, handheld devices such as mobile phones or tablet computers can have telecommunication capabilities, send and receive emails, maintain social networks, address book management, media playback, and other various functions and applications, among which the camera function It is a function commonly used by the public. In addition, the electronic device can also be connected with other hardware devices to achieve different functions.

[0003] Some external hardware devices may have some abnormalities. For example, an abnormal external hardware device will cause a large amount of p...
