Nigute ushobora guhitamo umushoferi ukwiranye na MOSFET?

Igihe cyo kohereza: Nyakanga-25-2024

Muri power switch hamwe nubundi buryo bwo gutanga amashanyarazi sisitemu yo gushushanya, abashushanya porogaramu bazitondera cyane umubare wibipimo byingenzi byaBYINSHI, nka on-off résistor, nini ya voltage ikora, ingufu nini zitemba. Nubwo iki kintu arikunegura, urebye ahantu hadakwiye bizatuma amashanyarazi atangwa adashobora gukora neza, ariko mubyukuri, ibi byujujwe gusa intambwe yambere,MOSFET ibipimo bya parasitike wenyine bifatwa nkikintu cyingenzi kibangamira amashanyarazi.

Nigute ushobora guhitamo umushoferi ukwiranye na MOSFET

Gutwara ako kanya MOSFETs hamwe na IC itanga amashanyarazi

Inzira nziza ya MOSFET yumushoferi ifite ingingo zikurikira:

. ku buryo bwihuse kandi ntihazabaho ihindagurika ryinshi-ryinshi ku mpande zizamuka.

Nigute ushobora guhitamo umushoferi ukwiranye na MOSFET (1)

(4) Kubaka byoroshye kandi byizewe byumuzunguruko wimodoka ifite imyenda mike.

(5) Ukurikije ibihe byihariye kugirango ukingire.

Kugenzura module itanga amashanyarazi, ibisanzwe ni amashanyarazi IC itwara MOSFET itaziguye. Porogaramu, igomba kwitondera disiki nini agaciro gakomeye k'ingufu zitemba, MOSFET yo gukwirakwiza ubushobozi 2 ibipimo nyamukuru. Ubushobozi bwa disiki ya power IC, ubunini bwa MOS ikwirakwiza, agaciro ka résistoriste irwanya agaciro bizabangamira igipimo cyo guhindura amashanyarazi MOSFET. Niba guhitamo ubushobozi bwa MOSFET bwo gukwirakwiza ari binini cyane, ubushobozi bwo gutanga amashanyarazi imbere ya IC imbere ntibihagije, bigomba kuba mumuzunguruko kugirango bigende neza ubushobozi bwo gutwara, akenshi ushyire kumashanyarazi ya totem pole kugirango uzamure ubushobozi bwo gutanga amashanyarazi IC Drive .
