DRV8847 Dual H-Bridge ọkwọ ụgbọ ala
Ngwa DRV8847 bụ onye na-anya ụgbọ ala abụọ H-bridge maka ngwa ụlọ ọrụ, ngwa ụlọ, ndị na-ebi akwụkwọ ePOS na ngwa mechatronics ndị ọzọ. Enwere ike iji ngwaọrụ a maka ịnya moto DC abụọ, moto bipolar stepper moto, ma ọ bụ ibu ndị ọzọ dị ka relays. PWM interface dị mfe na-enye ohere dị mfe na njikwa. Ngwa DRV8847 na-arụ ọrụ n'otu ọkụ ọkụ ma na-akwado oke ntinye ntinye sitere na 2.7 ruo 18 V.
Usoro mmepụta nke onye ọkwọ ụgbọ ala nwere ikike MOSFET nke N-ọwa ahaziri dị ka àkwà mmiri abụọ zuru ezu iji kwọọ ikuku moto ma ọ bụ àkwà mmiri anọ kwụụrụ onwe ya (na interface àkwà mmiri kwụụrụ onwe ya). Oge a kapịrị ọnụ na-achịkwa ọnụ ọgụgụ kachasị elu na akwa mmiri nke nwere ike ibu ibu 1-A (2-A na ọnọdụ yiri ya na ikpo ọkụ kwesịrị ekwesị, na 25 ° C TA).
A na-enye ọnọdụ ihi ụra nke dị ala iji nweta obere ihe dị ugbu a site na imechi ọtụtụ sekit dị n'ime. Tụkwasị na nke a, a na-enye scalar torque nke na-eme ka mmepụta ihe dị ugbu a na-agbanye ike site na ntinye ntinye dijitalụ. Njirimara a na-ahapụ onye njikwa ahụ ibelata ihe achọrọ ugbu a maka oriri ike dị ala.
