- Kukhazikitsa chipata cha logic
Malangizo Opanga: Kusintha kwa Level Shifting
Mukamagwiritsa ntchito 2N7000 pakusintha mulingo, onetsetsani kuti mukukokera koyenera. Mtengo wapakati wa 4.7kΩ mpaka 10kΩ umagwira ntchito bwino pamapulogalamu ambiri.
2. Kuyendetsa kwa LED ndi Kuwongolera Kuwala
Makhalidwe a 2N7000's osintha mwachangu amapangitsa kuti ikhale yabwino kwambiri pamapulogalamu owongolera a LED:
- PWM LED kuwongolera kuwala
- Kuyendetsa matrix a LED
- Chizindikiro chowongolera kuwala
- Njira zowunikira zotsatizana
| LED Current (mA) | RDS yovomerezeka (yayatsidwa) | Kutaya Mphamvu |
|---|---|---|
| 20mA | 5Ω pa | 2mw pa |
| 50mA pa | 5Ω pa | 12.5mW |
| 100mA | 5Ω pa | 50mW |
3. Mapulogalamu Oyang'anira Mphamvu
2N7000 imagwira ntchito bwino pamachitidwe osiyanasiyana owongolera mphamvu:
- Kusintha kwa katundu
- Magawo achitetezo a batri
- Kuwongolera kugawa mphamvu
- Zoyambira zofewa
Kuganizira Kofunika
Mukamagwiritsa ntchito 2N7000 pamagetsi, nthawi zonse ganizirani kuchuluka kwaposachedwa kwa 200mA ndikuwonetsetsa kuwongolera kokwanira kwamafuta.
Mfundo Zapamwamba Zoyendetsera Ntchito
Zofunikira pa Gate Drive
Kuyendetsa bwino pachipata ndikofunikira kuti 2N7000 igwire bwino ntchito:
- Magetsi ochepera a chipata: 4.5V kuti muwonjezere zonse
- Magetsi pachipata: 20V (mtheradi pazipita)
- Mphamvu yolowera pachipata: 2.1V
- Mtengo wa zipata: pafupifupi 7.5 nC
Kuganizira za Kutentha
Kumvetsetsa kasamalidwe ka matenthedwe ndikofunikira kuti mugwire ntchito yodalirika:
- Kulimbana ndi kutentha kwapakati: 312.5°C/W
- Kutentha kwakukulu kolowera: 150 ° C
- Kutentha kwa ntchito: -55 ° C mpaka 150 ° C
Kupereka Kwapadera kuchokera ku Winsok Electronics
Pezani ma MOSFET apamwamba kwambiri a 2N7000 okhala ndi mfundo zotsimikizika komanso chithandizo chonse chaukadaulo.
Malangizo Opanga ndi Njira Zabwino Kwambiri
Malingaliro a PCB Layout
Tsatirani malangizo awa kuti mupangire bwino PCB:
- Chepetsani kutalika kwa chipata kuti muchepetse inductance
- Gwiritsani ntchito ndege zoyenera pansi kuti muchepetse kutentha
- Ganizirani zozungulira zoteteza zipata zamapulogalamu omwe amakhudzidwa ndi ESD
- Gwiritsani ntchito kutsanulira kokwanira kwa mkuwa pakuwongolera kutentha
Magawo a Chitetezo
Tsatirani njira zodzitchinjiriza izi popanga zolimba:
- Chipata-source chitetezo zener
- Series pachipata resistor (100Ω – 1kΩ mmene)
- Reverse voltage chitetezo
- Zozungulira za snubber zonyamula katundu
Ntchito Zamakampani ndi Nkhani Zakupambana
2N7000 yatsimikizira kudalirika kwake m'mafakitale osiyanasiyana:
- Consumer Electronics: Zolumikizira zam'manja, ma charger
- Kuwongolera kwa Industrial: PLC zolumikizira, makina a sensor
- Magalimoto: Makina owongolera osafunikira, kuyatsa
- Zida za IoT: Zida zanzeru zakunyumba, ma sensor node
Kuthetsa Mavuto Odziwika
Mavuto Wamba ndi Mayankho
| Nkhani | Chifukwa Chotheka | Yankho |
|---|---|---|
| Chipangizo Chosasintha | Magetsi a Gate Osakwanira | Onetsetsani kuti magetsi a pachipata> 4.5V |
| Kutentha kwambiri | Adapitilira Mayeso Apano | Yang'anani katundu panopa, kusintha kuzirala |
| Kugwedezeka | Mawonekedwe Osauka/Gate Drive | Konzani masanjidwe, onjezani chotchinga pachipata |
