Ko nga huringa uta he whakaora mokowhiti, he whakawhiti hiko whakauru.Ka taea te whakamahi i enei huringa ki te 'momotu' i nga punaha iti e hiakai ana ki te hiko (i te wa e tatari ana) mo te whakahaere tohu-waahi ranei hei whakahaere i te raupapa hiko.I hangaia nga huringa uta i te wa i rongonui ai nga waea atamai;i te mea ka nui ake nga mahi a nga waea, ka hiahia ratou ki nga papa taiawhio kiato teitei ake, ka iti te waahi.Ka whakatauhia e nga whakahuri kawenga whakauru tenei raru: te whakahoki i te waahi poari ki te kaihoahoa me te whakauru i etahi atu mahi.
He aha nga painga o te whakawhiti uta whakauru ki te iahiko motuhake?
Kei roto i tetahi otinga motuhake ko te hiko-P whakarewa oxide semiconductor field effect transistor (MOSFET), he MOSFET hongere-N, me te parenga kume-ake.Ahakoa he otinga pono tenei mo te huri i nga reera hiko, he tapuwae nui tona.He maha atu nga otinga kiato kei te waatea inaianei, penei i nga huringa uta penei i te Texas Instruments TPS22915 - he tapuwae iti iho i te 1mm2!Ko te Whakaahua 2 e whakaatu ana i te whakatairitetanga o te whakatinanatanga a tetahi kaihoko me tenei otinga TI, i taea ai e te TPS22968 te whakaheke i tona tapuwae ma te neke atu i te 80% i te wa e whakauru ana i etahi atu ahuatanga penei i te tere piu me te tuku tere.
He aha te take e hiahia ana ahau ki te reiti whakamate?
Ko nga huringa kawenga TI katoa he reiti piu e whakahaere ana hei whakaiti i te kohu o te naianei, e mohiotia ana ano he 'mahi timatanga ngawari.Na roto i te whakanui i te tere o te utu o ona puritanga whakaputa, ka aukati te huringa uta i te ngaohiko tuku mai i te "maturuturu" na te tere o te utu o nga punga kawenga.Mo te roanga atu o nga korero mo te whakaheke i te o naianei, panuihia te tuhipoka tono: "Whakahaere i te Ope Taua".
He aha te Rapid Output Discharge?
Ko te mahi tuku tere tere, e waatea ana i runga i te nuinga o nga huringa kawenga, ka whakarite kia kore e maanu te utaina kua momotuhia, kua haua ranei.E whakaatu ana i te Whakaahua 3 i runga ake nei, ka whakawetohia e te urunga 'i' iti te huānga hongere ka whakahurihia te transistor paanga mara tuku (FET) ma te hurihuri.Ka hangaia he ara mai i te VOUT ki te GND, me te whakarite kia tere te whakahoki mai o te uta ki te ahua 0V 'atu' e mohiotia ana.
