Tsanangudzo yeTPS781
Iyo TPS781 mhuri yeyakaderera-dropout (LDO) regulators inopa mabhenefiti esimba rekupedzisira (IQ= 1µA), miniaturized kurongedza (2 × 2 SON-6), uye inosarudzika mbiri-nhanho kubuda voltage mazinga.Iyo inogadziriswa vhezheni inowanikwawo, asi haina simba rekuchinja voltage mazinga.
Iye VSETpini inobvumira mushandisi wekupedzisira kuchinja pakati pematanho maviri emagetsi pa-iyo-bhururuka kuburikidza neiyo microprocessor-inopindirana yekupinda.Iyi LDO yakagadzirirwa zvakanangana nebhatiri-powered application panodiwa mbiri-level voltages.Ne Ultralow IQ(1µA), microprocessors, memori makadhi, uye chiutsi madhigirii akanakira chishandiso ichi.
Iwo ekupedzisira-simba uye anosarudzwa maviri-chikamu chinobuda voltages anobvumira vanogadzira kugadzirisa mashandisiro emagetsi kune chaiwo maapplication.Vagadziri zvino vanogona kuchinjika kune yakaderera voltage level mubhatiri-powered dhizaini kana iyo microprocessor iri muhope mode, zvichiwedzera kudzikisa huwandu hwese simba rekushandisa.Iwo maviri voltage mazinga akaiswa preset pafekitori kuburikidza neyakasiyana dhizaini uchishandisa EPROM.Iyo EPROM tekinoroji inobvumira akawanda ekubuda voltage sarudzo pakati peVSETyakaderera (1.5V kusvika 4.2V) uye VSETyakakwirira (2.0V kusvika 3.0V) mune yakagadziriswa yakabuda vhezheni chete.Ona tafura iri mupepa rino re data kana kubvunza nemumiriri wefekitari yemunharaunda yako kuti uwane chaiwo mavhoti emagetsi uye ruzivo rwekuodha;hushoma hweodha huwandu hunogona kushanda.
Iwo TPS781 akatevedzana akagadzirwa kuti aenderane neTI MSP430 uye zvimwe zvakafanana zvigadzirwa.Iyo pini yekugonesa inoenderana neyakajairika CMOS logic.Iyi LDO yakagadzikana ine chero inobuda capacitor yakakura kupfuura 1.0µF.Naizvozvo, kuita kwechishandiso ichi kunoda kushoma bhodhi nzvimbo nekuda kweiyo miniaturized kurongedza uye inogona diki inobuda capacitor.Iyo TPS781 yakatevedzana IQ(1µA) inouyawo nekudzima kwemafuta uye muganho wazvino kuchengetedza mudziyo panguva yekukanganisa.Ese mapakeji ane tembiricha yekushandisa yeTJ= -40°C kusvika +125°C.Zvekushanda kwepamusoro-soro zvinoda sarudzo mbiri-level voltage, funga nezve TPS780 yakatevedzana, ine I.Qye500nA uye dynamic voltage kuyera.
1. Ndivanaani vashandi mudhipatimendi rako reR & D?Ndezvipi zvidzidzo zvako?
-R & D Mutungamiriri: gadzira chirongwa chekambani chenguva refu R & D uye ubate gwara rekutsvaga nekusimudzira;Tungamira uye tarisa r&d dhipatimendi kuti iite kambani r&d zano uye yegore R&D chirongwa;Dzora kufambira mberi kwekugadzirwa kwechigadzirwa uye gadzirisa chirongwa;Gadzira yakanakisa chigadzirwa chekutsvagisa uye timu yekusimudzira, yekuongorora uye yekudzidziswa ine chekuita nehunyanzvi vashandi.
R & D Maneja: gadzira chigadzirwa chitsva R & D kuronga uye kuratidza kugona kwechirongwa;Tarisa uye gadzirisa kufambira mberi uye kunaka kwer&d basa;Tsvagurudza kugadzirwa kwechigadzirwa chitsva uye kurudzira mhinduro dzinoshanda zvinoenderana nezvinodiwa nevatengi munzvimbo dzakasiyana
Vashandi veR&d: unganidza uye gadzirisa data rakakosha;Computer programming;Kuita zviedzo, bvunzo uye ongororo;Gadzirira zvinhu uye zvishandiso zvekuyedza, bvunzo uye ongororo;Rekodha data yekuyera, ita kuverenga uye gadzira machati;Ita ongororo dzenhamba
2. Ndeipi yako chigadzirwa tsvakurudzo uye budiriro pfungwa?
-Kufunga kwechigadzirwa uye sarudzo yechigadzirwa pfungwa uye yekuongorora tsanangudzo yechigadzirwa uye dhizaini dhizaini uye kusimudzira chigadzirwa kuyedzwa uye kusimbiswa kwekutanga kumusika.
