Wae Hiko IC Taketake LC898201TA-NH

whakaahuatanga poto:

Ko te LC898201 he LSI e whakahaere ana i nga motuka mo nga kaamera tirotiro i te wa kotahi ka peia te iris, te topa, te arotahi, me te huri i te ao/po.Ka honohia e ia nga waahanga urupare e rua mo te iris me te mana arotahi, me nga hiko hiko hikoi e rua mo te topa me te huri i te ao/po.Ano, i raro i te kowhiringa aratau, ka whakamahia te mana urupare mo te whakahaere iris me te mana motika stepper mo te topa, te arotahi, me te huri ao/po.

Kupu Whakataki

Ko te taraiwa motuka he pana, no te mea he tino nui te tere o te taraiwa motuka, he tino tiketike ranei te ngaohiko, a, kaore e taea te whakamahi i te whakawhiti whanui me nga waahanga hiko hei whakawhiti ki te whakahaere i te motuka.

Ko te mahi a te taraiwa motopaika: Ko te mahi a te taraiwa motuka e pa ana ki te huarahi ki te whakatutuki i te mana whakahaere o te tere tere motika ma te whakahaere i te koki hurihuri me te tere whakahaere o te motuka, kia tutuki ai te mana whakahaere o te huringa mahi.

Diagram ara iahiko iahiko taraiwa motoka: Ka taea te peia te ara iahiko taraiwa ma te rere, transistor hiko ranei, ma te whakamahi i te thyristor, te hiko MOS FET ranei.Hei urutau ki nga whakaritenga whakahaere rereke (penei i te waa mahi me te ngaohiko o te motuka, te whakaritenga tere o te motini, te mana whakamua me te whakamuri o te motuka DC, me etahi atu), me tutuki nga momo rereke o nga waahanga taraiwa motuka nga whakaritenga e tika ana.

Kare te waka hiko e timata i te wa e kaha ana, ka kaha ake te mahi ki te pana me te haere tahi me te tangi "koowao".Ko tenei ahuatanga ko te taura motopaika he poto poto na te whakapiri atu ki te hononga mariko, a ko te ahuatanga o te turaki i te kaata me nga raina waahanga e toru o te motini ka taea te wetewete me te ngaro, e tohu ana kua pakaru te kaiwhakahaere me te tika. whakakapia i te wa.Mena he uaua tonu ki te whakatinana, ko te tikanga he raru kei te motini, a tera pea na te poto o te porowhita o te motopaika e wera ana.
