智能功率控制應(yīng)用中的MCU選擇

　　電力供應(yīng)繼續(xù)提供新的功能，以提高效率，安全性和可管理性在苛刻的通信，工業(yè)和醫(yī)療應(yīng)用。越來越多的MCU的智能電源的關(guān)鍵要素和實(shí)施大范圍的控制、檢測、管理功能。看看一些更先進(jìn)的MCU硬件功能，以及它們簡化智能電源設(shè)計(jì)的方法，對于任何使用嵌入式系統(tǒng)的硬件設(shè)計(jì)者都是有用的。

　　本文將介紹幾個(gè)關(guān)鍵的MCU功能提供給嵌入式設(shè)計(jì)人員，解決智能電源的要求。在啟動(dòng)條件下的電源控制是一個(gè)明顯的要求，但傳感，測井和通信電源操作，也許是MCU的能力是最好的應(yīng)用領(lǐng)域。

　　Reliability， safety， and efficiency

　　Today reliability， safety， and efficiency are the key customer concerns for most power supply subsystems. However， these requirements often conflict with the traditional concerns of low cost， small board space， and ease of design. Using an advanced MCU as the controller for an intelligent power supply design can help mitigate some of these conflicts to create a more optimized design. Modern MCUs pack significant capabilities in a small board space， with little cost and the availability of reference designs， code examples， and development platforms dramatically simplify implementation.

　　Usually the MCU needs some external supporting devices to complete the design. Finding the correct combination of the right MCU and the right external devices is key to efficient implementations. A quick look at some important on-chip MCU functions and some of the common external devices that pair efficiently with an MCU will help guide you to your own device selections for an efficient implementation based on your custom requirements.
