Abstract

The invention discloses a charge baby circuit for a mobile phone. The circuit comprises a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a first triode, a second triode, a third triode, a luminous diode, a first potentiometer, a second potentiometer, a controllable precise stabilized power supply and a mobile phone battery. According to the invention, a constant voltage is adopted to charge the phone battery, so that the mobile phone can be charged continuously and stably; the luminous diode in the circuit is used for charging instructions, and when a rated value of the phone battery is reached through charging, a charging current is gradually reduced to zero, and the luminous diode is automatically out, so that the charging is completed, and the phenomenon of over-charging is avoided; and protection for the phone battery is facilitated, and at the same time, the circuit is simple in structure, few components and parts are used, so that the manufacturing cost is reduced, and the circuit has a popularization and application value.

Description

technical field [0001] The invention relates to an auxiliary device for a mobile phone, in particular to a power bank circuit for a mobile phone. Background technique [0002] In recent years, due to the popularization of mobile phones, the mobile game market has experienced explosive development. Various game developers, operators, service providers and mobile terminal manufacturers have started fierce competition, so various mobile games have been developed one after another. So that in many public places you can see people playing games with mobile phones, and mobile games are very power-hungry, and there must be enough power to maintain them. In this case, mobile phone power banks came into being. The charging circuit of the treasure is different. The ordinary constant voltage charging treasure in the prior art has a large charging current in the early stage of charging, which is not good for the battery of the mobile phone. The overcharging of mobile phones is not cond...
