Abstract
The present disclosure provides a management device for a charging circuit and a wireless terminal, which belong to the technical field of management control of a linear charging circuit. The device includes a power supply management module (), a buck switching voltage converter () and a linear charging circuit (). The power supply management module () includes an adjustable Low Dropout (LDO) linear regulator () and an Analog-to-Digital Converter (ADC) (), wherein the output terminal of the adjustable LDO linear regulator () is connected with the feedback terminal of the buck switching voltage converter () through a first preset resistor (R). The input terminal of the ADC () is connected with the anode of a battery (). The control terminal of the power supply management module () is connected with the control terminal of the linear charging circuit (). The output terminal of the buck switching voltage converter () is connected with the input terminal of the linear charging circuit (). The output terminal of the linear charging circuit () is connected with the anode of the battery (). With the device, the energy loss can be reduced and the whole power loss can be reduced.
