Yog tias peb piv cov hlaws LED rau ntau txhiab tus tub rog mloog lus, ces tus tsav tsheb IC yog "tus thawj coj" kev tawm tswv yim tom qab. Nws lub luag haujlwm yog los tswj qhov ci ntsa iab thiab xim ntawm txhua cov hlaws. Qhov kev ntseeg ntawm tus thawj coj no ncaj qha cuam tshuam rau kev ruaj ntseg thiab zoo ntawm tag nrho cov zaub. Yog li ntawd, kev ntseeg siab ntawm tus tsav tsheb IC yog qhov tseem ceeb.
Tsav IC kev ntsuas kev ntseeg tau npog txhua yam, los ntawm kev ua haujlwm hluav taws xob mus rau ib puag ncig kev hloov pauv. Ua ntej, nws ntsuas qhov tseeb ntawm nws cov hluav taws xob tsis zoo. Piv txwv li, qhov tseeb ntawm cov zis tam sim no yog qhov tseem ceeb; Qhov tseeb tsis txaus yuav ua rau cov xim tsis tu ncua thiab qhov ci tsis sib xws ntawm qhov screen. Cov neeg sim siv siab -cov cuab yeej ua kom raug los ntsuas seb IC qhov tso zis tam sim no phim tus nqi tsim ntawm qib grey nplai sib txawv.
Qhov thib ob, qhov kev ntsuam xyuas ib puag ncig adaptability yog sib npaug sib npaug. Tus tsav tsheb IC tau muab tso rau hauv qhov ntsuas kub thiab qis qis, ua haujlwm nyob rau hauv qhov kub siab tshaj ntawm -40℃mus rau tshaj 100℃los xyuas nws qhov kub coefficient-uas yog, qhov ruaj khov ntawm nws cov khoom tso tawm raws li qhov kub thiab txias. Ib tug "tus thawj tswj hwm" zoo yuav tsum nyob twj ywm thiab tawm tsam cov lus txib tsis hais qhov kub thiab txias.
Tsis tas li ntawd, tsav tsheb ICs yuav tsum tiv taus ntau yam kev cuam tshuam sab nraud thiab kev tawm tsam. Electrostatic paug tawm (ESD) kev tiv thaiv kab mob simulates hluav taws xob zoo li qub tsim tawm thaum ib tus neeg lossis cov cuab yeej tuaj yeem tiv tauj nrog IC, xyuas seb IC puas tuaj yeem tiv taus hluav taws xob tam sim ntawd yam tsis muaj kev puas tsuaj. Electromagnetic compatibility (EMC) kuaj xyuas seb IC radiates ntau dhau ntawm electromagnetic nthwv dej thaum lub sijhawm ua haujlwm, cuam tshuam nrog lwm yam khoom siv, thaum tseem ua kom nws tuaj yeem tiv taus qee theem ntawm kev cuam tshuam sab nraud electromagnetic. Tsuas yog tus tsav tsheb ICs uas dhau qhov kev ntsuam xyuas kev ntseeg siab no tuaj yeem suav hais tias tsim nyog "tus thawj coj," ua rau ntau lab tus LEDs los nthuav qhia qhov pom kev zoo nkauj hauv cov cheeb tsam nyuaj.
