由于MAX810L的復(fù)位門(mén)檻電平為4.65V，因此其RESET端輸出為高電平，迫使Q1關(guān)斷，從而使負(fù)載與輸入電源斷開(kāi)。MAX668通過(guò)外部反饋電阻網(wǎng)絡(luò)設(shè)定5V輸出電壓。當(dāng)輸出電壓超MAX810L的復(fù)位門(mén)檻電平時(shí)，其內(nèi)部單穩(wěn)電路開(kāi)始工作并延時(shí)約240ms。之后，MAX810L的輸出變低，使Q1導(dǎo)通。Q1導(dǎo)通之后，MAX810L一直監(jiān)測(cè)輸出電壓以確定輸出是否過(guò)流。過(guò)載將會(huì)導(dǎo)致輸出電壓下降，當(dāng)它低于MAX810L門(mén)檻電平時(shí)，MAX810L的輸出經(jīng)過(guò)20μs的延遲后由高變低，從而關(guān)斷Q1并使負(fù)載斷開(kāi)。由于MAX668的升壓作用，MAX810電源端電壓又會(huì)高于其門(mén)檻電平，240ms的復(fù)位延遲時(shí)間后，MAX810L輸出再次由高變低。

因?yàn)锽G1集電極與BG2基極相連，IC1又是BG2的基極電流Ib2。BG2又把比Ib2（Ib1）放大了β2的集電極電流IC2送回BG1的基極放大。如此循環(huán)放大，直到BGBG2完全導(dǎo)通。實(shí)際這一過(guò)程是“一觸即發(fā)”的過(guò)程，對(duì)可控硅來(lái)說(shuō)，觸發(fā)信號(hào)加入控制極，可控硅立即導(dǎo)通。導(dǎo)通的時(shí)間主要決定于可控硅的性能。可控硅一經(jīng)觸發(fā)導(dǎo)通后，由于循環(huán)反饋的原因，流入BG1基極的電流已不只是初始的Ib1，而是經(jīng)過(guò)BGBG2放大后的電流（β1*β2*Ib1）這一電流遠(yuǎn)大于Ib1，足以保持BG1的持續(xù)導(dǎo)通。此時(shí)觸發(fā)信號(hào)即使消失，可控硅仍保持導(dǎo)通狀態(tài)只有斷開(kāi)電源Ea或降低Ea，使BGBG2中的集電極電流小于維持導(dǎo)通的值時(shí)。

測(cè)它的正、反向電阻，電阻小時(shí)，萬(wàn)用表黑表筆接的是控制極G，可以用剛才演示用的示教板電路。接通電源開(kāi)關(guān)S，按一下按鈕開(kāi)關(guān)SB，燈泡發(fā)光就是好的，不發(fā)光就是壞的。測(cè)量方法鑒別可控硅三個(gè)極的方法很簡(jiǎn)單，根據(jù)P-N結(jié)的原理，只要用萬(wàn)用表測(cè)量一下三個(gè)極之間的電阻值就可以。陽(yáng)極與陰極之間的正向和反向電阻在幾百千歐以上，陽(yáng)極和控制極之間的正向和反向電阻在幾百千歐以上（它們之間有兩個(gè)P-N結(jié)，而且方向相反，因此陽(yáng)極和控制極正反向都不通）[1]？刂茦O與陰極之間是一個(gè)P-N結(jié)，因此它的正向電阻大約在幾歐-幾百歐的范圍，反向電阻比正向電阻要大？墒强刂茦O二極管特性是不太理想的，反向不是完全呈阻斷狀態(tài)的，可以有比較大的電流通過(guò)。
