Kev piav qhia rau DRV8871
Lub DRV8871 yog tus tsav tsheb brushed-DC rau cov tshuab luam ntawv, khoom siv, khoom siv, thiab lwm yam tshuab me me.Ob lub logic inputs tswj tus tsav tsheb H-bridge, uas muaj plaub N-channel MOSFETs uas tuaj yeem tswj cov motors bidirectionally nrog txog li 3.6-A ncov tam sim no.Cov inputs tuaj yeem ua bepulse-dav modulated (PWM) los tswj lub cev muaj zog ceev, siv cov kev xaiv ntawm cov qauv tam sim no.Kev teeb tsa ob qhov kev nkag siab qis nkag mus rau hom pw tsaug zog qis.
Lub DRV8871 ntaus ntawv tau tshaj tam sim no-txoj cai circuitry uas tsis siv qhov kev siv hluav taws xob analog lossis cov khoom siv sab nraud.Qhov kev daws teeb meem tshiab no siv tus qauv qis-qis, tsis muaj zog tiv thaiv los teeb tsa lub sijhawm tam sim no.Lub peev xwm los txwv qhov tam sim no mus rau qib paub tuaj yeem txo qhov kev xav tau ntawm lub cev muaj zog thiab cov peev txheej loj uas xav tau los tswj cov hluav taws xob ruaj khov, tshwj xeeb tshaj yog rau lub cev muaj zog startupand chaw nres tsheb.
Cov cuab yeej muaj kev tiv thaiv tag nrho los ntawm kev ua yuam kev thiab luv luv, suav nrog undervoltage (UVLO), overcurrent (OCP), thiab overtemperature (TSD).Thaum qhov teeb meem raug tshem tawm, cov cuab yeej cia li rov ua haujlwm li qub.
1. Leej twg yog cov neeg ua haujlwm hauv koj lub tuam tsev R & D?Koj qhov kev tsim nyog yog dab tsi?
-R & D Tus Thawj Coj: tsim lub tuam txhab cov phiaj xwm mus ntev R & D thiab tuav cov kev taw qhia ntawm kev tshawb fawb thiab kev loj hlob;Qhia thiab saib xyuas r&d department los siv lub tuam txhab r&d lub tswv yim thiab txhua xyoo R&D txoj kev npaj;Tswj kev txhim kho cov khoom lag luam thiab kho cov phiaj xwm;Teem cov khoom zoo tshaj plaws tshawb fawb thiab txhim kho pab pawg, tshawb xyuas thiab kev cob qhia txog cov neeg ua haujlwm.
R & D Tus Thawj Coj: ua cov khoom tshiab R & D txoj kev npaj thiab ua kom pom qhov ua tau ntawm txoj kev npaj;Saib xyuas thiab tswj qhov kev nce qib thiab ua haujlwm zoo ntawm r&d;Tshawb nrhiav kev tsim khoom tshiab thiab nthuav tawm cov kev daws teeb meem zoo raws li cov neeg siv khoom xav tau hauv ntau qhov chaw
R&d cov neeg ua haujlwm: sau thiab txheeb xyuas cov ntaub ntawv tseem ceeb;Computer programming;Ua cov kev sim, ntsuas thiab ntsuas;Npaj cov ntaub ntawv thiab khoom siv rau kev sim, kev sim thiab tshuaj xyuas;Sau cov ntaub ntawv ntsuas, ua cov lej thiab npaj cov kab kos;Ua cov ntawv tshawb fawb
2. Koj cov khoom tshawb fawb thiab kev tsim kho lub tswv yim yog dab tsi?
-Txoj kev xav thiab xaiv cov khoom lag luam lub tswv yim thiab kev ntsuam xyuas cov khoom txhais thiab cov phiaj xwm tsim thiab kev tsim cov khoom kuaj thiab kev siv tau tso rau kev lag luam
