♠ DRV8824 Stepper Motor Controller IC
I-DRV8824 ihlinzeka ngesixazululo esihlanganisiwe somshayeli wemoto samaphrinta, izikena, nezinye izinhlelo zokusebenza zemishini ezenzakalelayo.Idivayisi inabashayeli bebhuloho ababili be-H kanye ne-microstepping indexer, futhi ihloselwe ukushayela i-bipolar stepper motor.Ibhulokhi yomshayeli ophumayo iqukethe ama-MOSFET wamandla we-N-channel amiswe njengamabhuloho agcwele e-H ukuze ashayele ama-motor windings.I-DRV8824 iyakwazi ukushayela ifike ku-1.6 A yamanje kusuka ekuphumeni ngakunye (nge-heatsing efanele, ku-24 V naku-25°C).
Isixhumi esibonakalayo esilula se-STEP/DIR sivumela ukuxhumana okulula kumasekhethi okulawula.Izikhonkwane zemodi zivumela ukucushwa kwe-motor ngesinyathelo esigcwele kufika ku-1/32-step modes.Imodi yokubola iyalungiseka ukuze kusetshenziswe ukubola kancane, ukubola okusheshayo, noma ukubola okuxubile.Imodi yokulala enamandla amancane inikezwa evala ukujikeleza kwangaphakathi ukuze kuzuzwe ukudonsa okuphansi okupholile.Le modi yokulala ingasethwa kusetshenziswa iphinikhodi ye-nSLEEP ezinikele.
Imisebenzi yokuvala shaqa yangaphakathi ihlinzekelwe nge-overcurrent, i-short circuit, i-undervoltage lockout, kanye nezinga lokushisa elingaphezulu.Izimo zephutha zikhonjiswa ngephinikhodi ye-nFAULT.
