I-WS4695C
28V, Over-Voltage, Ukushintsha Kwamanje Komthwalo Wokuvikela Ngokushintsha Komkhawulo Wamanje

Izincazelo
I-WS4695C iyi-RON encane, ephansi, inkinobho yokulayisha isiteshi esisodwa enenani elilawulwayo lokubulala. Idivayisi ingasebenza ngevolumu yokufakatage ububanzi obungu-2.6 V ukuya ku-5.5 V futhi ingasetha umkhawulo wamanje ukusuka ku-0.1A ukuya ku-3.5A

Isikhathi esilawulwayo sokukhuphuka kwedivayisi kunciphisa kakhulu ukungena kokungena okubangelwa amandla omthwalo wenqwaba, ngaleyo ndlela kwehlise noma kuqedwe ukwehla kokuphakelwa kwamandla.I-WS4695C inomsebenzi Wokuvinjwa Okuhlehla Kwamanje (TRCB) ovimbela i-reverse current engafuneki ukusuka ku-VOUT ukuya ku-VIN phakathi no-ON. kanye nezifunda ze-OFF. Usayizi omncane kanye ne-RON ephansi kwenza idivayisi ifaneleke ukusetshenziswa kuzinhlelo zokusebenza ezikhawulelwe esikhaleni, ezisebenza ngebhethri. Umthamo wokufaka obanzitagUbubanzi beswishi buyenza ibe yisixazululo esiguquguqukayo sevolumu ehlukahlukenetage rails

Incazelo Eningiliziwe

I-Capacitor yokufaka
Ukukhawulela ivolumutagUma ukwehla kokunikezwayo okokufaka okubangelwa amaza esikhashana e-rush lapho iswishi ivuleka ibe i-capacitor yomthwalo okhishiwe noma i-short-circuit, i-capacitor idinga ukubekwa phakathi kwe-VIN ne-GND. I-ceramic capacitor engu-1-µF, CIN, ebekwe eduze nezikhonkwane, ngokuvamile yanele. Amanani aphezulu we-CIN angasetshenziswa ukuze kuqhutshekwe nokunciphisa umthamotage yehla phakathi nezinhlelo zokusebenza zamanje.

I-capacitor yokuphuma
I-capacitor ephumayo kufanele ibekwe phakathi kwe-VOUT namaphinikhodi we-GND. Le capacitor ivimbela i-parasitic board inductance ekuphoqeni i-VOUT ngaphansi kwe-GND uma iswishi ivuliwe. Le capacitor iphinde ivimbele i-reverse inrush current ekudaleni i-voltage spike engalimaza idivayisi esimweni esifushane se-VOUT.

Ukubikwa Kwephutha
Lapho kutholwa okweqile, i-#OC_FLA G ikhombisa iphutha ngokwenza kusebenze LOW.
Umkhawulo wamanje
Umkhawulo wamanje uqinisekisa ukuthi i-current ngokusebenzisa iswishi aweqi inani eliphakeme elimisiwe, kuyilapho ingakhawuleli inani elincane. Yamanje lapho umkhawulo wengxenye ulungiseka khona ngokukhethwa kwesiphikisa sangaphandle esixhunywe kuphinikhodi ye-ISET. Ulwazi lokukhetha i-resistor lutholakala esigabeni esingezansi. Idivayisi isebenza njengomthombo wamanje-manje uma umthwalo udonsa ngaphezu kwenani eliphakeme elibekwe idivayisi kuze kube yilapho kwenzeka ukuvala kwe-thermal. Idivayisi iyalulama uma izinga lokushisa lehla ngaphansi kwezinga lokushisa lomkhawulo.

Ngaphansi kwe-VoltagI-e Lockout (UVLO)
I-under-voltagI-e lockout ivala iswishi uma ivolumu yokufakatage yehla ngaphansi komkhawulo wokukhiya ngaphandle. Ngephinikhodi ye-EN esebenzayo, i-voltagUkukhuphuka ngaphezu komkhawulo we-UVLO kukhulula ukukhiya futhi kuvumela ukushintshwa.

Ukuvinjwa Kweqiniso Okuhlehlisiwe-Kwamanje
Isici sangempela sokuvimbela okubuyela emuva sivikela umthombo wokufaka ekugelezeni kwamanje kusuka kokuphumayo kuya kokokufakayo kungakhathaliseki ukuthi iswishi yokulayisha ivuliwe noma ivaliwe.
Ukuvalwa kwe-Thermal
Ukuvalwa kwe-thermal kuvikela ukufa kusuka kumazinga okushisa angaphakathi noma ngaphandle akhiqizwa ngokweqile. Ngesikhathi sezinga lokushisa elingaphezulu, iswishi iyacishwa. Iswishi ivuleka futhi ngokuzenzakalelayo uma izinga lokushisa le-die lehla ngaphansi kwezinga lokushisa lomkhawulo.

Ukubeka Umkhawulo Wamanje
Umkhawulo wamanje usethwe nge-resistor yangaphandle exhunywe phakathi kwe-ISET namaphinikhodi e-GND. Ingabalwa ngokuthi: Ukubekezelelana kwe-resistor okungu-1% noma ngaphansi kuyanconywa.
Umhlahlandlela wesakhiwo
Ukuze usebenze kahle kakhulu, yonke imikhondo kufanele ibe mfushane ngangokunokwenzeka. Ukuze kusebenze kahle kakhulu, okokufaka nokukhiphayo kufanele kubekwe eduze kwedivayisi ukuze kuncishiswe umthelela i-parasitic trace inductance engase ibe nawo ekusebenzeni okuvamile nokufushane. Ukusebenzisa ukulandelelwa okubanzi kwe-VIN, i-VOUT, ne-GND kusiza ukunciphisa imiphumela kagesi ye-parasitic kanye nokunciphisa i-case-to ambient impedance thermal.
