Vagadziri vedunhu vanofanirwa kunge vakafunga mubvunzo pakusarudza maMOSFET: Vanofanira kusarudza P-channel MOSFET kana N-channel MOSFET? Semugadziri, iwe unofanirwa kuda kuti zvigadzirwa zvako zvikwikwidze nevamwe vatengesi pamitengo yakaderera, uye iwe unofanirwawo kudzokorora kuenzanisa. Saka sei kusarudza? OLUKEY, mugadziri weMOSFET ane makore makumi maviri echiitiko, anoda kugovana newe.
Musiyano 1: maitiro ekuitisa
Hunhu hweN-chiteshi MOS ndehwekuti inobatidza kana Vgs yakakura kupfuura imwe kukosha. Inokodzera kushandiswa kana sosi yakadzikwa (yakaderera-kuguma drive), chero bedzi gedhi remagetsi richisvika 4V kana 10V. Kana ari maitiro eP-channel MOS, inobatidza kana Vgs iri pasi pehumwe kukosha, iyo inokodzera mamiriro ezvinhu kana sosi yakabatana neVCC (yakakwirira-kuguma drive).
Musiyano 2:MOSFETkuchinja kurasikirwa
Kunyangwe iri N-channel MOS kana P-channel MOS, pane-inopikisa mushure mekunge yabatidzwa, saka iripo inopedza simba pakuramba uku. Ichi chikamu chesimba rinopedzwa chinonzi conduction kurasikirwa. Kusarudza MOSFET ine diki pa-resistance kunoderedza kurasikirwa kwekuita, uye kuramba kweazvino-simba-MOSFETs kunowanzo kutenderedza makumi emamiriyoni, uye kune zvakare akati wandei mamiriyoni. Pamusoro pezvo, kana MOS ikabatidzwa nekudzimwa, haifanirwe kupedzwa ipapo ipapo. Pane kuderera kwemaitiro, uye kuyerera kwezvino kunewo kuwedzera.
Munguva iyi, kurasikirwa kweMOSFET ndicho chigadzirwa chemagetsi uye chazvino, chinonzi switching loss. Kazhinji kuchinja kurasikirwa kwakakura zvakanyanya kudarika kurasikirwa kwekufambisa, uye iyo yakakwirira yekushandura frequency, inowedzera kurasikirwa. Chigadzirwa chemagetsi uye chazvino panguva yekufambisa chakakura kwazvo, uye kurasikirwa kunokonzerwa zvakare kwakakura kwazvo, saka kupfupisa nguva yekuchinja kunoderedza kurasikirwa panguva yega yega conduction; kuderedza kushandura frequency kunogona kuderedza nhamba yekuchinja pane imwe unit nguva.
Musiyano wechitatu: MOSFET kushandiswa
Gomba rekufamba kweP-channel MOSFET rakaderera, saka kana saizi yejometri yeMOSFET uye kukosha kwese kweiyo voltage yekushandisa zvakaenzana, transconductance yeP-channel MOSFET idiki pane iyo yeN-channel MOSFET. Pamusoro pezvo, kukosha kwese kwechikumbaridzo voltage yeP-channel MOSFET yakakwira zvakati, inoda yakakwira yekushandisa voltage. P-channel MOS ine yakakura logic swing, refu yekuchaja uye yekuburitsa, uye diki mudziyo transconductance, saka kumhanya kwayo kwekushanda kwakadzikira. Mushure mekubuda kweN-channel MOSFET, mazhinji acho akatsiviwa neN-channel MOSFET. Nekudaro, nekuti P-channel MOSFET ine yakapusa maitiro uye yakachipa, mamwe epakati- uye madiki-madiki edhijitari ekudzora maseketi achiri kushandisa PMOS wedunhu tekinoroji.
Zvakanaka, ndizvo zvese zvekugovaniswa kwanhasi kubva kuOLUKEY, mugadziri wekurongedza weMOSFET. Kuti uwane rumwe ruzivo, unogona kutiwana paOLUKEYwebhusaiti yepamutemo. OLUKEY akatarisana neMOSFET kwemakore makumi maviri uye ane muzinda muShenzhen, Guangdong Province, China. Kunyanya kubatanidzwa mune yakakwira yazvino munda maitiro transistors, yakakwirira simba MOSFETs, hombe pasuru MOSFETs, diki voltage MOSFETs, diki pasuru MOSFETs, diki ikozvino MOSFETs, MOS field effect tubes, akaiswa MOSFETs, simba MOS, MOSFET mapakeji, epakutanga MOSFETs, akaiswa MOSFETs, nezvimwe. .Chigadzirwa chikuru chemumiririri ndiWINSOK.
