DRV8871DDAR SOP-8 Electronic Cheebtsam integrated circuit Tsav tsav nti

Lus piav qhia luv luv:

DRV8871DDAR 50-V, 3.6-A H-bridge tsav tsav nrog kev sib xyaw tam sim no

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.

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.
