Uruhare rwa MOSFETs mumuzunguruko

MOSFETSGira uruharemuguhindura imirongoni kugenzura umuzenguruko kuri no kuzimya no guhindura ibimenyetso.MOSFETS irashobora kugabanywa mubice bibiri: N-umuyoboro na P-umuyoboro.

Muri N-umuyoboroBYINSHIumuzenguruko, BEEP pin ni ndende kugirango ishoboze gusubiza buzzer, kandi hasi kugirango uzimye buzzer.P-umuyoboroBYINSHIkugenzura GPS module itanga amashanyarazi kuri no kuzimya, GPS_PWR pin iri hasi iyo kuri, module ya GPS ni amashanyarazi asanzwe, na muremure kugirango GPS module ikure.

UmuyoboroBYINSHImuri N-ubwoko bwa silicon substrate ku karere ka P + ifite bibiri: imiyoboro nisoko. Izi nkingi zombi ntizitwara hagati yazo, mugihe hari voltage nziza ihagije yongewe kumasoko iyo ihagaritswe, hejuru ya N-silicon yo hejuru y irembo izagaragara nkigice cya P cyinyuma, mumuyoboro uhuza imiyoboro nisoko. . Guhindura voltage kumuryango uhindura ubwinshi bwimyobo mumuyoboro, bityo ugahindura imiyoboro. Ibi byitwa P-umuyoboro wongera imbaraga za transistor.

Ibiranga NMOS, Vgs igihe cyose kirenze agaciro runaka izaba iriho, ikoreshwa kumasoko yashizwe hasi ya disiki ntoya, mugihe hateganijwe ko voltage yumuryango wa 4V cyangwa 10V kumurongo.

Ibiranga PMOS, bitandukanye na NMOS, bizafungura igihe cyose Vgs itarenze agaciro runaka, kandi irakwiriye gukoreshwa mugihe cya disiki ndende iyo isoko ihujwe na VCC. Ariko, kubera umubare muto wubwoko bwabasimbuye, hejuru-birwanya kandi nigiciro kinini, nubwo PMOS irashobora gukoreshwa muburyo bworoshye mugihe cyimodoka yo murwego rwohejuru, bityo rero muri disiki yo hejuru, muri rusange iracyakoresha NMOS.

Muri rusange,MOSFETSKugira ibitekerezo byinshi byinjira, byorohereze guhuza mu buryo butaziguye, kandi biroroshye guhimba mubice binini byahujwe.
