Abstract: With the diversified development of embedded systems, continuous technological advancements and the increasing demand for applications, the hardware platforms of embedded systems are also showing a diversified trend. From the initial simple processors to the current multi-core processors, such as FPGAs, ASICs and so on, the hardware platforms of embedded systems have become increasingly complex. Power integrity, especially, faces severe challenges as the number of power channels in embedded systems increases, power consumption surges, power-on timing requirements become more stringent, and reset signal classification becomes more complex. Therefore, intelligent digital power health management units have become increasingly important. This paper implements 14-channel power-on sequence control, voltage monitoring, temperature monitoring, reset signal and configuration signal control based on TI's digital power on-sequence control circuit UCD9090 and digital PWM system control circuit UCD9244. Compared with traditional intelligent digital power health management solutions, this scheme offers flexible control, simple implementation, and requires no complex coding. The application of this solution in the system has shortened the product's time to market.

引言

隨著嵌入式系統(tǒng)的硬件平臺(tái)呈現(xiàn)出多元化的發(fā)展趨勢(shì),從最初的簡(jiǎn)單處理器,到現(xiàn)在的FPGA、ASIC、多核處理器、多核異構(gòu)處理器、MPSOC等,嵌入式系統(tǒng)的硬件平臺(tái)越來(lái)越復(fù)雜。電源完整性面臨著嚴(yán)峻的挑戰(zhàn),尤其電源通道越來(lái)越多、功耗急劇增加、上電時(shí)序要求苛刻、復(fù)位信號(hào)分類復(fù)雜,從而導(dǎo)致智能數(shù)字電源健康管理單元顯得越來(lái)越重要[1]。傳統(tǒng)智能數(shù)字電源健康管理單元方案一般采用一個(gè)MCU、CPLD或CPU作為主處理器[2],配套AD采集、運(yùn)放、Flash及顯示等外設(shè),并通過(guò)編寫(xiě)代碼利用輪詢、中斷等方式實(shí)現(xiàn)對(duì)特殊事件的及時(shí)處理功能,如及時(shí)檢測(cè)周邊溫度、過(guò)壓、欠壓、過(guò)流及省電模式等,有時(shí)還需實(shí)時(shí)檢測(cè)并顯示出來(lái),且支持將錯(cuò)誤事件進(jìn)行實(shí)時(shí)記錄。如此一個(gè)復(fù)雜健康管理系統(tǒng)對(duì)硬件及軟件的要求極高、開(kāi)發(fā)難度大[3],從而導(dǎo)致大多數(shù)設(shè)計(jì)師放棄了智能數(shù)字電源健康管理單元,導(dǎo)致系統(tǒng)對(duì)異常事件處理能力喪失,甚至導(dǎo)致整個(gè)系統(tǒng)燒毀[4]。

基于以上傳統(tǒng)智能數(shù)字電源健康管理單元的缺點(diǎn),本文提出基于TI公司的數(shù)字電源上電順序控制電路UCD9090、數(shù)字PWM系統(tǒng)控制電路UCD9244實(shí)現(xiàn)多路電源電壓輸出控制、上電順序控制[5]、電壓監(jiān)控、溫度監(jiān)控、復(fù)位信號(hào)和配置信號(hào)的控制及異常事件記錄log功能。此方案與傳統(tǒng)智能數(shù)字電源健康管理方案相比此方案控制靈活、實(shí)現(xiàn)簡(jiǎn)單,無(wú)需編寫(xiě)代碼,并且可以通過(guò)PMBUS接口實(shí)時(shí)交互數(shù)據(jù)并圖形化顯示電壓、電流、溫度及功耗。此方案在系統(tǒng)中的應(yīng)用縮減了產(chǎn)品的上市時(shí)間,并使硬件系統(tǒng)及軟件系統(tǒng)極度簡(jiǎn)化[6],提升了系統(tǒng)的可靠性及穩(wěn)定性。
