♠ DRV8876 H-Bridge Motor Driver Ndi Integrated Current Sense and Regulation
Gulu la zida za DRV887x ndi madalaivala osinthika amitundu yosiyanasiyana. Zipangizozi zimagwirizanitsa ndi N-channel H-mlatho, mpope wachargeregulator, zomverera zapano ndi kuwongolera, kutulutsa kofananira kwapano, ndi chitetezo chozungulira. Pampu yojambulira imathandizira kuchita bwino polola zonse ziwirima MOSFET apamwamba komanso otsika kwambiri a N-channels ndi 100% yothandizira kuzungulira ntchito. Banja la zida zimabwera mu pini-to-pini, zosankha za RDS (pa) kuti zithandizire zolemetsa zosiyanasiyana ndikusintha pang'ono.
Kuzindikira kwamakono kophatikizana kumalola dalaivala kuti aziwongolera momwe magalimoto amayendera panthawi yoyambira komanso zochitika zazikulu. Malire apano atha kukhazikitsidwa ndi reference yamagetsi yakunja yosinthika. Kuphatikiza apo, zidazi zimapereka zotulutsa zomwe zimayenderana ndi kuchuluka kwa magalimoto. Izi zitha kugwiritsidwa ntchito kuzindikira mayendedwe agalimoto kapena kusintha kwa katundu. Kuphatikizika komweku kumagwiritsa ntchito kamangidwe ka magalasi amkati, kuchotsa kufunikira kwa chopinga chachikulu cha shunt, malo osungira bolodi ndikuchepetsa mtengo wamakina.
Njira yogona yamphamvu yocheperako imaperekedwa kuti mukwaniritse mawonekedwe amphamvu kwambiri potseka ma circuit ambiri amkati. Zida zachitetezo chamkati zimaperekedwa pakutsekera kwamagetsi (UVLO), pampu yachaji pansi pa voteji (CPUV), kutuluka mopitilira muyeso (OCP), ndi kutentha kwa chipangizo (TSD). Zolakwa zimawonetsedwa pa nFAULT.
