♠ DRV8876 H-Bridge Motor Driver Ine Yakabatanidzwa Yazvino Sense uye Regulation
Iyo DRV887x mhuri yemidziyo inochinjika mota madhiraivha emhando dzakasiyana dzekushandisa. Midziyo iyi inobatanidza N-channel H-bhiriji, pombi yekuchajaregulator, ikozvino sensing uye regulation, ikozvino proportional kubuda, uye kudzivirira wedunhu. Iyo pombi yekuchaja inonatsiridza kugona nekubvumidza kune ese ari maviriyepamusoro-side uye yakaderera-side N-channels MOSFETs uye 100% duty cycle rutsigiro. Mhuri yemidziyo inouya mupini-kune-pini, scalable RDS (pa) sarudzo dzekutsigira mitoro yakasiyana ine kushoma dhizaini shanduko.
Yakabatanidzwa yazvino yekunzwa inobvumira kuti mutyairi adzore mota iripo panguva yekutanga uye yakakwirira mitoro zviitiko. Muganho wazvino unogona kuiswa neinogadziriswa yekunze voltage reference. Pamusoro pezvo, iwo maturusi anopa inobuda yazvino yakaenzana kune mota mutoro wazvino. Izvi zvinogona kushandiswa kuona mota stall kana shanduko mumamiriro ekuremerwa. Iyo yakasanganiswa yazvino sensing inoshandisa yemukati yazvino girazi architecture, ichibvisa kudiwa kwesimba hombe shunt resistor, kuchengetedza bhodhi nzvimbo uye kuderedza system mutengo.
Iyo yakaderera-simba yekurara modhi inopihwa kuti iwane ultralow quiescent yazvino kudhirowa nekuvhara mazhinji emukati wedunhu. Yemukati yekudzivirira maficha anopihwa yekugovera undervoltage yekuvhara (UVLO), pombi yekuchaja pasi pevolti (CPUV), kubuda overcurrent (OCP), uye kupisa kwemudziyo (TSD). Mhosva mamiriro anoratidzwa pa nFAULT.
