Lub Rooj Tswjhwm Saib Xyuas Roj Teeb Ua Haujlwm li cas

Lithium roj teeb kev tiv thaiv boards muaj ntau yam circuits thiab tsis nyob ntawm cov IC siv, voltage, thiab lwm yam. Cov feem ntau siv tiv thaiv ICs yog 8261, DW01 ntxiv, CS213, GEM5018, thiab lwm yam. Ntawm lawv, Seiko's 8261 series muaj qhov tseeb zoo dua, thiab tau kawg, tus nqi yog kim dua. Cov tom kawg yog tag nrho los ntawm Taiwan. Lub khw muag khoom hauv tsev siv DW01 ntxiv thiab CS213. Cov hauv qab no yog ib qho kev piav qhia ntawm DW01 ntxiv nrog MOS raj 8205A (8pin):

Cov txheej txheem ua haujlwm ib txwm muaj ntawm lithium roj teeb tiv thaiv pawg thawj coj saib raws li hauv qab no:

Thaum lub cell voltage nyob nruab nrab ntawm 2.5V thiab 4.3V, thawj thiab peb tus pins ntawm DW01 ob leeg tso zis siab (sib npaug rau cov khoom voltage), thiab tus pin thib ob voltage yog 0V. Lub sijhawm no, qhov voltage ntawm 1st thiab 3rd pins ntawm DW01 yuav raug siv rau 5th thiab 4th pins ntawm 8205A feem. Ob lub tshuab hluav taws xob hauv 8205A nyob rau hauv lub xeev ua haujlwm vim tias lawv cov G ncej txuas nrog qhov hluav taws xob los ntawm DW01, uas yog, Ob lub tshuab hluav taws xob tau qhib. Lub sijhawm no, tus ncej tsis zoo ntawm lub xovtooj txuas ncaj qha mus rau P- davhlau ya nyob twg ntawm lub rooj tiv thaiv kev tiv thaiv, thiab lub rooj tsav xwm tiv thaiv muaj qhov tso tawm hluav taws xob.
