Kev piav qhia rau DRV8842
DRV8842 muab ib qho kev sib xyaw tsav tsheb daws teeb meem rau cov tshuab luam ntawv, tshuab luam ntawv, thiab lwm yam khoom siv siv tshuab.Cov cuab yeej muaj ib tus neeg tsav tsheb H-bridge, thiab yog npaj los tsav ib lub DC lub cev muaj zog, ib lub kauj ntawm lub cev muaj zog, lossis lwm yam khoom thauj.Cov tso zis tsav tsheb thaiv muaj N-channel zog MOSFETs teeb tsa raws li H-bridge.DRV8842 tuaj yeem muab tau txog li 5-A ncov lossis 3.5-A RMS cov zis tam sim no (nrog rau cov cua sov kom zoo ntawm 24 V thiab 25 ° C).
Cais tawm tswv yim los tswj nws tus kheej ib nrab ntawm H-bridge yog muab.
Internal shutdown functions yog muab rau overcurrent tiv thaiv, luv luv-circuit tiv thaiv, undervoltage lockout, thiab overtemperature.
TheDRV8842 muaj nyob rau hauv 28-pin HTSSOP pob nrog PowerPAD (Eco-friendly: RoHS & tsis muaj Sb/Br).
Rau tag nrho cov pob khoom muaj, saib qhov kev txiav txim ntxiv rau qhov kawg ntawm daim ntawv teev cov ntaub ntawv.
