GUSABA
- TI MSP430 Ongeraho Porogaramu
- Imbaraga zingufu hamwe nuburyo bwo gutangiza gahunda
- Inzego ebyiri zingufu zuburyo bwo kuzigama imbaraga
- Wireless Handsets, Smartphone, PDAs, Abakinnyi ba MP3, nibindi bicuruzwa bikoreshwa na Bateri
Ibindi bicuruzwa byose ni umutungo wa ba nyirabyo
Ibisobanuro kuri TPS781
Umuryango wa TPS781 wubuyobozi bugabanuka (LDO) utanga inyungu zingufu za ultralow (I.Q= 1µA), gupakira miniaturike (2 × 2 SON-6), hamwe no guhitamo ibyiciro bibiri bisohoka voltage urwego.Impinduka ishobora guhinduka nayo irahari, ariko ntabwo ifite ubushobozi bwo guhindura urwego rwa voltage.
V.SHAKApin yemerera umukoresha wa nyuma guhinduranya hagati ya voltage ebyiri murwego rwo kuguruka binyuze muri microprocessor-ihuza ibyinjijwe.Iyi LDO yagenewe byumwihariko porogaramu ikoreshwa na bateri aho hakenewe voltage ebyiri.Hamwe na ultralow I.Q.
Ultralow-power kandi ihitamo ibyiciro bibiri-bisohoka voltage yemerera abashushanya guhitamo ingufu zikoreshwa mubikorwa byihariye.Abashushanya ubu barashobora kwimuka kurwego rwo hasi rwa voltage mugushushanya gukoreshwa na bateri mugihe microprocessor iri mubitotsi, bikagabanya muri rusange gukoresha ingufu za sisitemu.Inzego ebyiri za voltage ziteganijwe muruganda binyuze mubwubatsi budasanzwe ukoresheje EPROM.Tekinike ya EPROM yemerera ibisohoka byinshi bya voltage hagati ya V.SHAKAhasi (1.5V kugeza 4.2V) na V.SHAKAmuremure (2.0V kugeza 3.0V) muburyo bwasohotse gusa.Reba imbonerahamwe iri muriyi mpapuro cyangwa ubaze uhagarariye uruganda rwaho kugirango ubone amahitamo ya voltage hamwe no gutumiza amakuru;ingano ntarengwa yo gutumiza irashobora gusaba.
Urukurikirane rwa TPS781 rwashizweho kugirango ruhuze TI MSP430 nibindi bicuruzwa bisa.Gushoboza pin irahuza na logique isanzwe ya CMOS.Iyi LDO ihamye hamwe nibisohoka byose birenze 1.0µF.Kubwibyo, gushyira mubikorwa iki gikoresho bisaba umwanya muto wibibaho kubera gupakira miniaturike hamwe nubushobozi buke bushobora gusohoka.Urukurikirane rwa TPS781 I.Q.Amapaki yose afite ubushyuhe bwo gukora bwa T.J= -40 ° C kugeza kuri + 125 ° C.Kubikorwa-byimikorere isaba ibyiciro bibiri-bya voltage ihitamo, tekereza kuri TPS780, hamwe na I.Qya 500nA hamwe no gupima imbaraga za voltage.
1. Ni bande bakozi mu ishami rya R & D?Ni ubuhe bushobozi bwawe?
-R & D Umuyobozi: gutegura gahunda yigihe kirekire yikigo no gusobanukirwa icyerekezo cyubushakashatsi niterambere;Kuyobora no kugenzura ishami rishyira mubikorwa ingamba za sosiyete na gahunda ya R&D yumwaka;Kugenzura iterambere ryibicuruzwa no guhindura gahunda;Shiraho ibicuruzwa byiza byubushakashatsi niterambere, kugenzura no guhugura abakozi ba tekiniki bijyanye.
Umuyobozi wa R & D: kora ibicuruzwa bishya R & D hanyuma werekane ko bishoboka gahunda;Kugenzura no gucunga iterambere nubuziranenge bwakazi;Kora ubushakashatsi ku bicuruzwa bishya kandi utange ibisubizo bifatika ukurikije ibyo umukiriya asabwa mubice bitandukanye
Abakozi & gukusanya: gukusanya no gutondekanya amakuru yingenzi;Porogaramu ya mudasobwa;Gukora ubushakashatsi, ibizamini nisesengura;Tegura ibikoresho nibikoresho byo kugerageza, kugerageza no gusesengura;Andika amakuru yo gupima, gukora ibarwa no gutegura imbonerahamwe;Kora ubushakashatsi bwibarurishamibare
2. Niki gitekerezo cyawe cyo gukora ubushakashatsi nibitekerezo byiterambere?
- Igitekerezo cyibicuruzwa no guhitamo ibicuruzwa nibisobanuro byerekana ibicuruzwa nibishushanyo mbonera byumushinga no kugerageza ibicuruzwa bitezimbere no kwemeza isoko
