Description
本發明係有關於一種電源供應裝置之判斷機制,尤指一種電源供應裝置、可判斷電源供應裝置的種類之可攜式電子裝置及其相關判斷方法。 The present invention relates to a judgment mechanism of a power supply device, and more particularly to a power supply device, a portable electronic device capable of determining the type of the power supply device, and related determination methods.
目前市面上的手機均依照廠牌或型號而有各自專屬的手機充電器,例如:H廠牌的手機充電器僅能提供給H廠牌的手機使用,而無法對N廠牌或M廠牌的手機進行充電。然而,中國信產部推行手機充電器連接器介面採用通用串列匯流排(Universal Serial Bus,USB)的規格,亦即同一個充電器可用來對不同廠商、不同型號的手機充電。 At present, mobile phones on the market have their own mobile phone chargers according to the brand or model. For example, the mobile phone charger of the H brand can only be used for the mobile phone of the H brand, but not for the N or M brand. The phone is charging. However, China Ministry of Information Industry's implementation of the mobile phone charger connector interface uses the Universal Serial Bus (USB) specification, which means that the same charger can be used to charge different manufacturers and different models of mobile phones.
一般來說,USB的傳輸介面具有五個傳輸端點,其分別係為VBUS端點、D+端點、D-端點、ID端點以及GND端點。對於中國大陸規格的充電器而言,其係將D+端點與D-端點在充電器的本體內短路以作為中國大陸規格充電器的識別特徵。 In general, the USB transmission interface has five transmission endpoints, which are VBUS endpoint, D+ endpoint, D-endpoint, ID endpoint, and GND endpoint. For Chinese mainland chargers, the D+ terminal and D-end are short-circuited in the body of the charger to be the identification feature of the Chinese mainland charger.
而當手機的USB連接器連接至一電子裝置的USB連接器時,手機必須具備能夠正確地判別該電子裝置的種類的能力,接下來才能夠進行正確的運作,例如,當該電子裝置係為一充電器時,該手機便可利用該充電器來對本身進行充電;又例如,當該電子裝置並非為一充電器而係為一電腦主機時,該手機便可與該電腦主機進行資料傳輸的動作。此外,採用同一個充電器來對不同廠商、不同型號 的手機充電的概念固然方便,但市面上所充斥的充電器種類太繁雜無法對其品質進行控管。若是手機可允許被任一廠商的充電器進行充電而不加以限制時,手機可能會因為被持續充電而導致其內部的電容器電壓超出電容額定值而損毀電容器,更甚者,可能導致其他元件損害或者無法符合安全規範而產生危險。因此,目前亟需能夠判別該電子裝置的種類的可攜式電子裝置以及相關判別機制。 When the USB connector of the mobile phone is connected to the USB connector of an electronic device, the mobile phone must have the ability to correctly determine the type of the electronic device, and then the correct operation can be performed, for example, when the electronic device is When the charger is used, the mobile phone can use the charger to charge itself; for example, when the electronic device is not a charger and is a computer host, the mobile phone can perform data transmission with the computer host. Actions. In addition, the same charger is used for different manufacturers and different models. The concept of charging a mobile phone is convenient, but the types of chargers that are flooded on the market are too complicated to control its quality. If the mobile phone can be charged by any manufacturer's charger without limitation, the mobile phone may damage the capacitor because its internal capacitor voltage exceeds the capacitor rating due to continuous charging, and even worse, may cause other components. Danger due to damage or failure to comply with safety regulations. Therefore, there is a need for a portable electronic device capable of discriminating the type of the electronic device and a related discrimination mechanism.

接下來,將搭配第6圖所示之各步驟、第5圖所示之各元件以及第1圖~第4圖所示之電源供應裝置100~400來說明如何判斷該電源供應裝置的種類。首先,將一電源供應裝置連接至可攜式電子裝置500(步驟604),此時,第一端點511(亦即VBUS端點)之電壓位準係為高邏輯位準(步驟606)。接著,第三判斷單元533會判斷第四端點514(亦即ID端點)之電壓位準(步驟608),當第四端點514之電壓位準係為低邏輯位準時,判斷電路530會判定該電源供應裝置係為第3圖所示之電源供應裝置300(步驟610);而當第四端點514之電壓位準係為高邏輯位準時,第二判斷單元532會進行第二判斷結果DR2之偵測(步驟620~622)。 Next, how to determine the type of the power supply device will be described with reference to the respective steps shown in FIG. 6, the components shown in FIG. 5, and the power supply devices 100 to 400 shown in FIGS. 1 to 4. First, a power supply device is connected to the portable electronic device 500 (step 604). At this time, the voltage level of the first terminal 511 (ie, the VBUS endpoint) is a high logic level (step 606). Next, the third determining unit 533 determines the voltage level of the fourth endpoint 514 (ie, the ID endpoint) (step 608). When the voltage level of the fourth endpoint 514 is a low logic level, the determining circuit 530 The power supply device is determined to be the power supply device 300 shown in FIG. 3 (step 610); and when the voltage level of the fourth terminal 514 is at the high logic level, the second determining unit 532 performs the second The result of the determination DR2 is detected (steps 620-622).
接下來,先透過電阻元件R1來拉高第二端點512之電壓位準(步驟620),而第二判斷單元532會判斷第三端點513(亦即D-端點)之電壓位準來產生第二判斷結果DR2(步驟622)。當第三端點513之電壓位準係為高邏輯位準時,須先透過電阻元件R2來拉低第三端點513之電壓位準(步驟630),並接著利用第一判斷單元531來判斷第三端點513之電壓位準(步驟632)。當第三端點513之電壓位準係為高邏輯位準時,判斷電路530會判定該電源供應裝置係為電源供應裝置400;而當第三端點513之電壓位準係為低邏輯位準時,判斷電路530會判定該電源供應裝置係為電源供應裝置100。 Next, the voltage level of the second end point 512 is first raised through the resistive element R1 (step 620), and the second determining unit 532 determines the voltage level of the third end point 513 (ie, the D-end point). The second determination result DR2 is generated (step 622). When the voltage level of the third terminal 513 is a high logic level, the voltage level of the third terminal 513 must be first pulled through the resistance element R2 (step 630), and then judged by the first determining unit 531. The voltage level of the third terminal 513 (step 632). When the voltage level of the third terminal 513 is a high logic level, the determining circuit 530 determines that the power supply device is the power supply device 400; and when the voltage level of the third terminal 513 is a low logic level. The determination circuit 530 determines that the power supply device is the power supply device 100.
另一方面,當步驟622中的第二判斷結果DR2顯示第三端點513之電壓位準係為低邏輯位準時,第四判斷單元534會判斷可攜式電子裝置500是否為一USB配置裝置(步驟640)。若是可攜式電子裝置500係為一USB配置裝置時,判斷電路530會判定該電源供應裝置為一電腦主機(步驟642);若是可攜式電子裝置500並非為一USB配置裝置時,判斷電路530會判定該電源供應裝置為非電腦主機之一充電器(亦即一般市售的充電器)(步驟644)。 On the other hand, when the second determination result DR2 in step 622 shows that the voltage level of the third terminal 513 is a low logic level, the fourth determining unit 534 determines whether the portable electronic device 500 is a USB configuration device. (Step 640). If the portable electronic device 500 is a USB configuration device, the determination circuit 530 determines that the power supply device is a computer host (step 642); if the portable electronic device 500 is not a USB configuration device, the determination circuit The 530 determines that the power supply device is a non-computer host charger (i.e., a commercially available charger) (step 644).
簡而言之,可透過第5圖所揭露之可攜式電子裝置500搭配第6圖所揭露之判斷機制,來分辨與可攜式電子裝置500相連接的電源供應裝置為何者(例如第1圖~第4圖之電源供應裝置100~400)。 In short, the portable electronic device 500 disclosed in FIG. 5 can be used with the judgment mechanism disclosed in FIG. 6 to distinguish the power supply device connected to the portable electronic device 500 (for example, the first Figure ~ Figure 4 power supply device 100 ~ 400).
