Inkcazelo ye-TPS781
Usapho lwe-TPS781 lwabalawuli be-low-dropout (LDO) banikezela ngezibonelelo zamandla aphantsi kakhulu (IQ= 1µA), ukupakishwa kweminiaturized (2 × 2 SON-6), kunye namanqanaba ombane akhethiweyo amanqanaba amabini emveliso.Uguqulelo oluhlengahlengiswayo lukwakhona, kodwa alunawo amandla okutshintsha amanqanaba ombane.
I-VSETiphini ivumela umsebenzisi wokugqibela ukuba atshintshe phakathi kwamanqanaba amabini ombane kwi-fly ngegalelo elihambelana ne-microprocessor.Le LDO yenzelwe ngokukodwa usetyenziso olunamandla ebhetri apho kufuneka umbane wenqanaba elimbini.Nge-ultralow IQ(1µA), ii-microprocessors, iimemori khadi, kunye nezixhobo zokuqaphela umsi zezona zixhobo zifanelekileyo kwesi sixhobo.
Amandla aphantsi kakhulu kunye nokukhethwa kombane wenqanaba elimbini livumela abaqulunqi ukuba benze usetyenziso lwamandla ngokweemfuno zokusebenza ezithile.Abaqulunqi ngoku banokutshintshela kwinqanaba elisezantsi lombane kuyilo olunamandla ebhetri xa i-microprocessor ikwimowudi yokulala, ngakumbi ukunciphisa ukusetyenziswa kwamandla ngokubanzi.Amanqanaba ombane amabini asetwa kwangaphambili kumzi-mveliso ngokusebenzisa i-architecture eyodwa usebenzisa i-EPROM.Ubuchwephesha be-EPROM buvumela iinketho ezininzi zombane wokuphuma phakathi kweVSETephantsi (1.5V ukuya ku-4.2V) kunye ne-VSETphezulu (2.0V ukuya 3.0V) kuguqulelo lwemveliso esisigxina kuphela.Bona itheyibhile kolu xwebhu lwedatha okanye udibane nommeli wefektri yasekhaya malunga nokhetho oluchanekileyo lombane kunye nolwazi lokuodola;umyinge owuodolo omncinci unokusebenza.
Uthotho lwe-TPS781 luyilelwe ukuba luhambelane ne-TI MSP430 kunye nezinye iimveliso ezifanayo.Iphini yokuvula iyahambelana nengqiqo ye-CMOS eqhelekileyo.Le LDO izinzile nayo nayiphi na imveliso yecapacitor enkulu kuno 1.0µF.Ke ngoko, ukuphunyezwa kwesi sixhobo kufuna indawo encinci yebhodi ngenxa yokupakishwa kweminiaturized kunye necapacitor encinci enokubakho.Uhlobo lwe-TPS781 IQ(1µA) kwakhona iza nokuvalwa kwe-thermal kunye nomda wangoku ukukhusela isixhobo ngexesha leempazamo.Zonke iipakethe zinomgangatho wobushushu osebenzayo we-TJ= -40°C ukuya +125°C.Kusetyenziso oluphezulu olufuna ukhetho lwamanqanaba amabini ombane, qwalasela uthotho lwe-TPS780, kunye ne-I.Qye-500nA kunye nokunyuka kwamandla ombane oguqukayo.
