Abstract

The invention relates to a circuit structure having functions of both a flash lamp and a signal lamp and a mobile terminal. The circuit structure includes a power management chip, an LED lamp and a battery, an input interface of a power input circuit in the power management chip is connected with a negative electrode of the LED lamp, a positive electrode of the LED lamp is connected with a positive electrode of the battery, and the power input circuit is also connected with an external controller used for controlling working current of the power input circuit. The LED lamp is controlled through the built-in circuit of the power management chip, functions of a signal lamp are added while functions of a flash lamp are realized, design is simple, current consumption is low, user experience is enriched while product functions are enriched, and enterprise design cost is reduced.

Description

technical field [0001] The present application relates to the technical field of signal light circuits, and in particular to a circuit structure and a mobile terminal with functions of both a flash light and a signal light. Background technique [0002] At present, most mobile terminals on the market, such as mobile phones, use a combination of breathing light chip + LED signal light as the commonly used signal light. The design of this solution is relatively complicated and the cost is relatively high. There are also some mobile phones that use a rear camera flash as a signal light, but this solution has simple functions and consumes a lot of current. [0003] The commonly used solution is a multi-device solution that uses a combination of power management chip + flashlight + signal light. This solution has a complex design and many chips, which increases the board area and hardware cost. Contents of the invention [0004] The purpose of this application is to propose a ...
