Kev piav qhia rau TPS2052B
Lub TPS20xxB fais fab kev faib hluav taws xob hloov pauv yog npaj rau kev siv qhov twg hnyav capacitive loads thiab luv circuits yuav raug ntsib.Cov khoom siv no suav nrog 70-mΩ N-channel MOSFET lub zog hloov pauv rau lub zog xa hluav taws xob uas xav tau ntau lub zog hloov pauv hauv ib pob.Txhua qhov hloov pauv yog tswj los ntawm lub logic enableinput.Lub rooj vag tsav yog muab los ntawm lub twj tso kua mis sab hauv tsim los tswj lub zog hloov lub sijhawm nce thiab lub caij nplooj zeeg kom txo qis tam sim no surges thaum hloov.Lub twj tso kua mis them nyiaj yuav tsum tsis muaj cov khoom siv sab nraud thiab tso cai rau kev ua haujlwm ntawm cov khoom siv tsawg li 2.7 V.
Thaum cov zis load tshaj qhov tam sim no-txheej pib lossis luv luv tam sim no, cov cuab yeej txwv cov zis tam sim no mus rau theem kev nyab xeeb los ntawm kev hloov mus rau hauv hom tsis tu ncua tam sim no, rub lub overcurrent (OCx) logic tso zis qis.Thaum nruam hnyav overloads thiab luv luv Circuit Court ua rau lub zog dissipation nyob rau hauv lub hloov, ua rau lub hlws ris kub torise, ib tug thermal tiv thaiv Circuit Court kaw tawm qhov hloov mus los tiv thaiv kev puas tsuaj.Rov qab los ntawm thermalshutdown yog tsis siv neeg thaum lub cuab yeej txias txaus.Internal circuitry xyuas kom meej tias qhov hloov hluav taws xob tseem tawm mus txog thaum muaj hluav taws xob input voltage.Qhov hloov hluav taws xob faib hluav taws xob no yog tsim los teeb tsa kev txwv tam sim no ntawm 1 A (ib txwm).
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
