DRV8847 Dual H-Bridge Motor Driver
Chipangizo cha DRV8847 ndi dalaivala wapawiri wa H-mlatho wamagalimoto ogwiritsira ntchito mafakitale, zida zapakhomo, osindikiza a ePOS, ndi ntchito zina zamakina.Chipangizochi chitha kugwiritsidwa ntchito poyendetsa ma mota awiri a DC, mota ya bipolar stepper, kapena katundu wina monga ma relay.Mawonekedwe osavuta a PWM amalola mawonekedwe osavuta ndi wowongolera.Chipangizo cha DRV8847 chimagwira ntchito pamagetsi amodzi ndipo chimathandizira mitundu yosiyanasiyana yamagetsi kuyambira 2.7 mpaka 18 V.
Gawo lotuluka la dalaivala limapangidwa ndi ma MOSFET amphamvu a N-channel opangidwa ngati milatho iwiri yathunthu ya H kuti aziyendetsa ma windings kapena milatho inayi yodziyimira payokha (mu mawonekedwe odziyimira pawokha).Nthawi yokhazikika imayang'anira nsonga yapamwamba mumlatho yomwe imatha kuyendetsa katundu wa 1-A (2-A munjira yofananira ndi kutentha koyenera, pa 25 ° C TA).
Njira yogona yamphamvu yocheperako imaperekedwa kuti muzitha kujambula pang'onopang'ono potseka mbali zambiri zamkati.Kuphatikiza apo, torque scalar imaperekedwa yomwe imakulitsa zomwe zikutuluka kudzera pa pini ya digito.Izi zimalola wowongolera kuti achepetse zomwe zimafunikira kuti muchepetse mphamvu zamagetsi.
Ntchito zodzitchinjiriza zamkati zimaperekedwa pakutsekereza-kutsekeka, kutetezedwa mopitilira muyeso pa FET iliyonse, chitetezo chozungulira chachifupi, kuzindikira katundu wotseguka, komanso kutentha kwambiri.Zolakwika zimawonetsedwa ndi pini ya nFAULT.Mtundu wa chipangizo cha I 2C (DRV8847S) uli ndi zowunikira mwatsatanetsatane.
