嵌入式系统中电源管理电路的设计与实现

Design and Implementation of Embedded System Power Management Circuitry

针对大部分嵌入式系统的电池电源管理问题,设计了一种为嵌入式系统,尤其是对应用在手持式和便携式设备的嵌入式系统进行电源管理的电路单元模块。在本系统中,电源管理电路单元以MAX8903为核心,具有输入范围宽、体积紧凑、外围电路简单、工作效率较高等优势,该电源管理电路可以在嵌入式系统中用来管理电池充电、电源选择、电源检测等,很好的实现了电源管理单元的功能需求。

For most embedded systems battery power management problem, a kind of embedded systems, especially for applications in handheld and portable devices power management circuit unit modules was designed. In this system, the MAX8903 power management circuit unit to the core, with a wide input range, compact size, the external circuit is simple, high efficiency and other advantages, the power management circuits in embedded systems can be used to manage battery charging, power options, power testing, etc., to achieve a good power management unit functional requirements.
