Ibisobanuro kuri TPS2595
Umuryango wa TPS2595xx ya eFus (ibikoresho bya FET bishyushye bishyirwa hamwe) ni uburyo bwo kurinda umuzenguruko hamwe no gucunga ingufu mumashanyarazi.Ibikoresho bitanga uburyo bwo kurinda ibintu byinshi ukoresheje ibice bike byo hanze kandi ni uburyo bukomeye bwo kwirinda ibintu birenze urugero, imiyoboro migufi, umuvuduko wa voltage, hamwe na inrush ikabije.
Ibisohoka bigarukira kurwego rushobora gushyirwaho hamwe na résistoriste yo hanze.Ntibishoboka kubona ibisobanuro nyabyo byibisohoka umutwaro mugupima voltage igabanuka acrossthe imipaka irwanya.Porogaramu hamwe na inrush yihariye ibisabwa birashobora gushiraho igipimo cyo gusohora hamwe na capacitori imwe yo hanze.Ibintu birenze urugero bigarukira byihuta byimbere byimbere kugirango bigerweho neza, nta bikoresho byo hanze bisabwa.Ihinduka ryaTPS259573 ritanga uburyo bwo gushyiraho umukoresha-wasobanuye hejuru ya volvoltage yo kurenga.
Imikorere yihuse yo gusohora irashobora gushyirwa mubikorwa muri TPS2595x5 muguhuza pin ya OUT kuri QOD pin.
Ibikoresho birangwa no gukora hejuru yubushyuhe bwa –40 ° C kugeza kuri + 125 ° C.
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
