Tsanangudzo yeDRV8871
Iyo DRV8871 mudziyo ibrashi-DC mota mutyairi wemaprinta, midziyo, midziyo yemumaindasitiri, uye mimwe michina midiki.Mabhii maviri epfungwa anodzora mutyairi weH-bhiriji, ane ina N-channel MOSFETsiyo inokwanisa kudzora mota nenzira mbiri inosvika 3.6-A peak ikozvino.Izvo zvinopinda zvinogona bepulse-width modulated (PWM) kudzora kumhanya kwemota, uchishandisa sarudzo yezvino-kuora modes.Setting both inputs low inopinda yakaderera-simba yekurara modhi.
Iyo DRV8871 mudziyo une advanced current-regulation circuitry isingashandise analog voltage referensi kana yekunze sense resistor.Iyi novel mhinduro inoshandisa yakajairwa-inodhura-yakaderera, yakaderera-simba resistor kuseta iyo currentthreshold.Kugona kudzikamisa ikozvino kune inozivikanwa nhanho kunogona kudzikisa zvakanyanya sisitimu simba rezvinodiwa uye yakawanda capacitance inodiwa kuchengetedza yakagadzikana voltage, kunyanya kune mota startupa uye stall mamiriro.
Chishandiso ichi chakachengetedzwa zvizere kubva kuzvikanganiso uye mapfupi maseketi, anosanganisira undervoltage (UVLO), overcurrent (OCP), uye overtemperature (TSD).Kana iyo yekukanganisa yabviswa, chishandiso chinotangazve kushanda kwakajairika.
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.
