Load keyboards yog qhov chaw txuag, kev sib txuas hluav taws xob hloov pauv.Cov keyboards no tuaj yeem siv los 'disconnect' lub zog-tshaib plab subsystems (thaum nyob rau hauv standby hom) los yog rau point-of-load tswj los pab txhawb lub zog sequencing.Load keyboards tau tsim thaum lub xov tooj smartphones nrov;Raws li cov xov tooj ntxiv kev ua haujlwm ntau dua, lawv xav tau ntau dua qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.Integrated load switches daws qhov teeb meem no: rov qab board qhov chaw rau tus tsim qauv thaum integrating ntau functionality.
Dab tsi yog qhov zoo ntawm kev hloov pauv kev sib xyaw ua ke piv rau kev sib cais Circuit Court?
Ib qho kev daws teeb meem raug suav nrog P-channel hlau oxide semiconductor field effect transistor (MOSFET), N-channel MOSFET, thiab rub-up resistor.Thaum qhov no yog qhov pov thawj kev daws teeb meem rau kev hloov hluav taws xob, nws muaj qhov hneev taw loj.Ntau cov kev daws teeb meem tam sim no muaj, xws li cov khoom siv thauj khoom xws li Texas Instruments TPS22915 - lawv muaj hneev taw tsawg dua 1mm2!Daim duab 2 qhia txog kev sib piv ntawm ib tus neeg siv khoom siv nrog qhov kev daws teeb meem TI no, uas ua rau TPS22968 txo nws cov hneev taw los ntawm ntau dua 80% thaum sib koom ua ke ntau yam xws li kev tswj lub viav vias thiab cov zis tawm sai.
Vim li cas kuv thiaj xav tau tus nqi tswj hwm?
Tag nrho TI load keyboards muaj kev tswj kev viav vias kom txo qis tam sim no, tseem hu ua 'soft start function.Los ntawm maj mam nce tus nqi them ntawm nws cov zis capacitors, qhov hloov pauv ntawm cov khoom siv tiv thaiv cov khoom siv hluav taws xob los ntawm "poob" vim qhov them sai sai ntawm cov khoom thauj khoom.Yog xav paub ntxiv txog kev txo qis tam sim no, thov nyeem daim ntawv thov: "Managing Inrush Current".
Rapid Output Discharge yog dab tsi?
Qhov tso zis tawm ceev ceev muaj nuj nqi, muaj nyob rau ntawm cov khoom siv thauj khoom feem ntau, kom ntseeg tau tias qhov kev sib txuas lossis cov khoom siv tsis raug cai tsis ntab.Raws li pom nyob rau hauv daim duab 3 saum toj no, ib tug tsawg 'rau' input tig tawm lub ntsiab channel thiab tig rau lub discharging teb nyhuv transistor (FET) ntawm lub inverter.Qhov no tsim txoj hauv kev los ntawm VOUT mus rau GND, kom ntseeg tau tias cov khoom thauj tuaj yeem rov qab sai sai rau lub xeev 0V 'tawm'.
