Load switches inochengetedza nzvimbo, inosanganisa magetsi switch.Aya ma switch anogona kushandiswa 'kubvisa' simba-ane nzara subsystems (kana iri mumodhi yekumira) kana yekudzora-yekuremedza kudzora kutevedza kwemagetsi.Kuchinja kwemutoro kwakagadzirwa apo mafoni akave akakurumbira;sezvo mafoni akawedzera kushanda kwakawanda, aida yakakwirira density circuit board uye nzvimbo yakava shoma.Yakabatanidzwa mitoro inochinja inogadzirisa dambudziko iri: kudzorera bhodhi nzvimbo kune mugadziri uku uchibatanidza kushanda kwakawanda.
Ndeapi mabhenefiti eiyo yakasanganiswa mitoro switch kana ichienzaniswa neye discrete circuit?
Yakajairika discrete mhinduro ine P-channel simbi oxide semiconductor field effect transistor (MOSFET), N-channel MOSFET, uye inodhonza-up resistor.Kunyange iyi iri mhinduro yakasimbiswa yekuchinja magetsi njanji, ine tsoka yakakura.Mamwe macompact solutions ave kuwanikwa, senge load switch senge Texas Instruments TPS22915 - vane tsoka isingasviki 1mm2!Mufananidzo 2 unoratidza kuenzanisa kwekuita kwemutengi mumwechete neiyi mhinduro yeTI, iyo yakagonesa iyo TPS22968 kudzikisa tsoka yayo neanopfuura 80% uku ichibatanidza zvimwe zvinhu senge inodzorwa swing rate uye nekukurumidza kubuda kubuda.
Sei ndichida chiyero chekuuraya chakadzora?
Yese TI inotakura switch ine inodzorwa swing rate yekudzikisa inrush ikozvino, inozivikanwawo se 'soft start function.Nekuwedzera zvishoma nezvishoma muyero wekuchaja weyakabuda capacitors, chinja chekutakura chinodzivirira magetsi ekupa kubva "kudonha" nekuda kwekukurumidza kuchaja kwemacapacitors ekutakura.Kuti uwane rumwe ruzivo nezve kudzikisa inrush ikozvino, ndapota verenga iyo application note: "Managing Inrush Yazvino".
Chii chinonzi Rapid Output Discharge?
Iyo inokurumidza kubuda yekuburitsa basa, inowanikwa pane yakawanda mitoro switch, inova nechokwadi chekuti yakadzimwa kana yakaremara mutoro haina kuyangarara.Sezvinoratidzwa mumufananidzo 3 pamusoro, iyo yakaderera 'pa' yekuisa inodzima chiteshi chinhu uye inobatidza yekuburitsa munda effect transistor (FET) kuburikidza neinverter.Izvi zvinogadzira nzira kubva kuVOUT kuenda kuGND, kuve nechokwadi chekuti mutoro unogona kukurumidza kudzoserwa kune inozivikanwa 0V 'off' state.
