Abstract

The invention provides a low-power-consumption stable charging box circuit, which comprises a charging chip, a battery, a dormancy module, a Hall switch, a voltage stabilizing chip and a main control chip, and is characterized in that the charging chip is connected with the main control chip, the charging chip is connected with the battery, the battery is respectively connected with the dormancy module and the Hall switch, and the voltage stabilizing chip is connected with the main control chip. The output end of the Hall switch is respectively connected with the dormancy module and the main control chip, the output end of the main control chip is connected with the dormancy module, the output end of the dormancy module is connected with the voltage stabilizing chip, and the output end of the voltage stabilizing chip is connected with the main control chip. The charging box has the beneficial effect that the standby power consumption of the charging box is reduced.

Description

technical field [0001] The invention relates to a charging box, in particular to a low power consumption and stable charging box circuit. Background technique [0002] TWS earphones can be said to be a product that conforms to the trend of the times. In addition to canceling the 3.5mm interface on the mobile phone end and the cumbersome earphone cable on the earphone end, it can also realize functions such as dual-use, easy to carry, and intelligent voice. With the continuous improvement of people's daily life needs and the continuous optimization of portable methods, traditional earphones have been difficult to meet the needs in use. So with the continuous development of smart hardware, TWS earphones have become more and more popular in the market. With the release of Apple's Airpods, the wireless Bluetooth headset market has reached a climax. Since the left and right earphones of TWS earphones have no physical connection characteristics, and TWS earphones generally do no...
