Sei pasina gadhi rimwe chete rinogona kushandiswa munhevedzano

Kana akawanda zvikamu zve lithium bhatiri rekugadzirisa bhodhi zvakabatana munhevedzano, anotevera matambudziko anogona kuitika:

1: Kuchaja: tora bhatiri 4.2 V voltage kugadzirisa, senge B plate cout yekuchaja pombi kugadzirisa, kusingaperi kwemukati kuramba, panguva ino, iyo chubhu ikozvino yakachekwa-yekubvisa mapoinzi, uye general chikamu chimwe chete chelithium bhatiri rekuchengetedza bhodhi field effect tube pressure yakanyanya. yakaderera, saka inogona kudonha, asi nekuda kweiyo yekuchaja mamiriro, kubhadharisa ikozvino kuderera mukuwedzera kune ese ebhatiri voltage, general haizoratidzi overpressure phenomenon), mushure mekugadzirisa uye imwe yekuchaja chubhu B, yekuchaja voltage inogona kuwedzera imwe chete VDD yekugadzirisa pani yepamusoro inogona kutaridzika yakawandisa, zvichikonzera kukuvadzwa kwekugadziriswa kweiyo yakabatanidzwa pani B.

2: kubuda: kufungidzira bhatiri voltage 2.7V kuchengetedza, sekugadzirisa ndiro Dout kuchaja tube kugadzirisa, kusingaperi mukati mekudzivirira, panguva ino, ndiyo ikozvino tube poyiti, ino nguva kana dunhu mukati mune mabhatiri matanhatu, saka chubhu ichave. 25 V voltage, denderedzwa rakasvibirira pamufananidzo Dout field effect chubhu yakapfava kukundikana, saka, kunyange mukugadzirisa basa, Kunewo mamwe mabhiza ayo, kana akanganisa zvachose, achave ane simba rakasimba kuburikidza nekurasikirwa nekugadzirisa. Mushure mekunge chubhu yagadziriswa, kumanikidzwa kwemashure kubva kuV kumagumo ebhodhi A kusvika kuVSS kumagumo ebhodhi A yakakwirira se25V, uye kumanikidzwa kwemashure kubva kuV kusvika kumagumo eVDD inenge 21V, iyo inogona kukonzera zvachose chip. kukuvara.

Kumwe kuongorora kuri pamusoro, zvakakosha kucherechedza kuti iyo munda mhedzisiro chubhu mbiri bhutsu mudziyo, pasi pemamiriro akajairwa, kunyangwe isina magetsi ekutyaira, magetsi emagetsi anogona zvakare kuve ekutungamira museve icon zviitiko, senge pamufananidzo uri pamusoro pedout yakakwira voltage uye yazvino inogona kuva. yakadzoserwa, museve dout yakaderera kugona, parizvino chete zvinoenderana nebasa remuseve zvakare, asi kwakanangana nekuita kwemuseve kwapera. Naizvozvo, DOUT ndiyo inobuda inodzora terminal.

Mumamiriro ezvinhu akajairika, tinogona kufamba munzira yemiseve tisingawedzere zvinogoneka, asi pachave nekudonha kwekumanikidza kweinenge 0.3V. Saka, kubvisa kudonha kwemagetsi emukati uye kuwedzera mwero wepamusoro, kudonha kwemagetsi mukati memuseve gwara kunoswedera kune mashoma mamilivolts kusvika kumakumi emamilivolts. Naizvozvo, MOSFETT iri maviri-gwara rekudzora mudziyo.
