OMNIVISION WS4694C Pūoko Whakaahua 
Whakaahuatanga
Ko te WS4694C he iti, he iti te RON, he whakawhiti kawenga hongere kotahi me te tere o te patu. Ka mahi te taputapu i runga i te voli whakaurutagte awhe o te 2.6 V ki te 5.5 V. Ka tautokohia e te taputapu te rohe o naianei mai i te 0.05 A ki te 2 A.
Ko te pikinga o te wa o te taputapu ka tino whakaheke ake i te tere o te waa na te nui o te kaha o te utaina, na reira ka whakaiti, ka whakakorehia ranei te heke o te hiko. Ko te WS4694C he mahinga Whakamuri-Naianei Tuturu (TRCB) e arai ana i te au whakamuri e kore e hiahiatia mai i te VOUT ki te VIN i nga wa ON me OFF. Ko te iti me te iti o te taputapu RON kua hoahoatia mo nga waahi e kaha ana ki te whakamahi i te pākahiko. Ko te whanui whakauru voltagKo te awhe o te whakawhiti ka waiho hei otinga whaihua mo te maha o nga momo voltage reera.
Kei te waatea te WS4694C i roto i te kete CSP-9L. Ko nga hua paerewa he Pb-kore me te Halogen-kore.

Nga korero tono
Punga Whakauru
Hei whakawhāiti i te voltagka taka ki runga i te toha whakauru na nga ia o te tere tere i te wa e ka ana te pana, me whakanoho he puri ki waenga i te VIN me te GND. Ka taea te whakamahi i nga uara teitei ake o te CIN hei whakaiti ake i te voltage heke i roto i nga tono teitei o naianei.
Pūnga pūnga putanga
Me whakanoho he punga putanga ki waenga i te VOUT me te titi GND. Ko te pūnga iahiko ka aukati i te whakaurunga o te papa pirinoa kia kore e pehia te VOUT i raro i te GND ina ka ana te pana. Ka aukati hoki te pūnga iahiko whakamuri mai i te voltaghe titi ka taea te pakaru i te taputapu mena he poto te VOUT.
Purongo Hapa
I te kitenga o te nui o naianei, ka tohuhia e #OC_FLAG te he ma te whakahohe i te LOW.
Whakawhāiti o nāianei
Ko te tepe o naianei ka whakarite kia kaua e neke ake te naianei o te whakawhiti i te uara kua whakaritea morahi, me te kore e whakaiti i te uara iti. Ko te naianei e taea ai te whakarite te rohe o te waahanga ma te kowhiringa o te parenga o waho e hono ana ki te titi ISET. Ko nga korero mo te whiriwhiri i te parenga ka kitea i te waahanga i raro nei. Ka mahi te taputapu hei puna o naianei tonu ina kumea atu te uta i te uara teitei kua whakaritea e te taputapu tae noa ki te wa e tutakina ana te waiariki. Ka ora ake te taputapu mena ka heke te pāmahana mate ki raro i te paepae.
I-raro o te Voltage Maukati
Te Raro-Voltage Maukati (UVLO) ka whakaweto i te whakakā mena ka uru te voltagka taka ki raro i te paepae kati. Ki te whakahohe te titi EN, te vol tāurutagka piki ki runga ake i te paepae UVLO ka tukuna te maukati ka taea te huri.
Parai Whakamuri-Naianei Pono
Ko te ahuatanga aukati whakamuri-naianei pono ka tiaki i te puna whakauru mai i te rere o naianei mai i te putanga ki te whakauru ahakoa kei te ka te pana uta, kaore ranei.
Whakaweto Ngawha
Ma te katinga waiariki e tiaki i te mate mai i te wera nui o roto, o waho ranei. I te wa o te wera nui, ka weto te pana. Ka huri aunoa te pana ki te heke iho te pāmahana o te mate ki raro i te pāmahana paepae.
Te whakatau i te Tepe o Naianei
Kua whakaritea te rohe o naianei me tetahi parenga o waho e hono ana i waenga i nga titi ISET me GND.
Ko te tepe onāianei ka tatauhia ko enei e whai ake nei:

Aratohu Tahora
Mo te mahi pai, me poto nga tohu katoa ka taea. Kia tino whai hua, me noho tata ki te taputapu nga punga whakaurunga me te whakaputanga ki te whakaiti i te awenga ka pa mai pea te inductance tohu parapara ki runga i nga mahi noa me te ara-poto. Ma te whakamahi i nga tohu whanui mo te VIN, VOUT, GND ka awhina i te whakaiti i nga paanga hiko parataiao me te arai wera-a-waahanga.
