Abstract

The invention relates to the technical field of electronics and discloses a prompt circuit and electronic equipment. The prompt circuit is applied to the electronic equipment; a control unit controlsa first output end to output high level and a prompt unit begins to work when a power management chip determines that a VBUS pin of a USB interface outputs charging voltage and a first detection terminal of the control unit detects successful handshake of an external charger and the USB interface based on a charging protocol; and the control unit controls a second output end to output high level and the prompt unit stops working when a second detection terminal of the control unit detects that a battery is full of electricity. According to the prompt circuit and the electronic equipment provided by the embodiment of the invention, an accurate charging prompt can be made according to the actual charging condition, the problem of false charging or the problem that the charging prompt cannotbe made is effectively solved and the cost is reduced.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a prompt circuit and electronic equipment. Background technique [0002] With the development of electronic technology, the functions of various electronic devices, such as mobile phones and tablets, are becoming more and more powerful, and they occupy an increasingly important position in people's life and work. In the current electronic equipment, in order to improve the user experience and meet the needs of users, designers usually equip the electronic equipment with a charging indicator light, and the driver chip controls the on and off of the charging indicator light, so that when there is a charger connected After charging the electronic device, the user can determine the current charging status of the electronic device according to the charging indicator light. [0003] But the inventor finds that there are at least the following problems in the prior art: the cost of...
