Abstract

The invention discloses a charging indication device and a terminal. The charging indication device includes a control switch, a light-emitting unit, a power supply unit, and a control interface connected with the charging device; to provide power for the light-emitting unit; the control switch includes a first control switch, a second control switch, and a third control switch; the control interface includes a first control interface, a second control interface, and a third control interface; the first control interface and the third control interface The control interface is respectively connected with the first control switch; the second control interface is connected with the second control switch; the first control switch, the second control switch and the third control switch are connected with the light-emitting unit, and the second control switch is connected with the third control switch Both are grounded, which solves the problems of complicated control process and high cost in the existing charging instructions. The present invention also discloses a terminal. By implementing the above scheme, discrete devices are used to effectively reduce costs.

Description

technical field [0001] The present invention relates to the field of terminals, and more particularly, to a charging indication device and a terminal. Background technique [0002] At present, there are more and more various electronic devices. In order to make the electronic devices portable, the electronic devices are generally powered by batteries. The battery is generally a rechargeable secondary battery, which requires frequent charging of the battery of the electronic device. [0003] When charging the battery, no matter whether the electronic device is turned off or turned on, the battery charging status should be indicated. In the existing charging instructions, the charging conditions are different when the charging is turned on and off, so it is necessary to design a separate charging and shutdown charging, for example, when shutdown charging, it is more accurate to use the charging IC, and continue to use the charging IC control to indicate the battery charging s...
