The design of portable charger
Abstract
With the rise of smart phones and other intelligent products such as ipad, people are increasingly inseparable from intelligent products. Intelligent products become irreplaceable items. The rise of smart products and wifi and 4G communication network at the same time the rapid development is inseparable. But in the use of wifi or 4G network when the phone on the power consumption greatly improved, when going out, on our lives has brought great inconvenience. Mobile phone battery life restricts the development of smart phones. While the mobile power is the proposed solution for the life of smart mobile products.
For portable charger, this design is divided into hardware and software part.Hardware part of the STMicroelectronics ARM (STM32F103) as a controller;Hardware part of the STMicroelectronics ARM (STM32F103) for the controller; to take TP4056 for the power management IC to achieve the power management of mobile power management functions (including charging function, charging process of overshoot protection and temperature detection); take TPS6123X series as a power Discharge boost core IC.The software part uses Keil as the compilation environment, and through the J-LINK simulator software on-line simulation and download the program.
Key words: portable charger; Power management IC; STM32F103; DC-DC booster
