♠ DRV8824 Stepper Motor Pule IC
O le DRV8824 o loʻo tuʻuina atu se fofo faʻapipiʻi taʻavale afi mo lomitusi, sikola, ma isi mea faʻaoga masini. O le masini e lua ta'avale alalaupapa H ma se microstepping indexer, ma ua fa'amoemoe e fa'aola se afi ta'avale lapo'a. O le poloka aveta'avale o lo'o i ai N-channel power MOSFET ua fa'atulagaina e pei o H-alalaupapa atoa e fa'aulu ai ta'avale afi. O le DRV8824 e mafai ona ave i luga le 1.6 A o le taimi nei mai mea taʻitasi (faʻatasi ai ma le vevela lelei, i le 24 V ma le 25 ° C).
O se fa'aoga faigofie STEP/DIR e faigofie ai ona fa'afeso'ota'i i ta'amilosaga fa'atonutonu. O pine fa'ata'ita'iga e mafai ai ona fa'atulaga le afi i la'asaga atoa e o'o atu ile 1/32-step modes. E mafai ona fetuutuunai le faiga pala ina ia mafai ai ona faaaoga le pala lemu, le pala vave, po o le pala fefiloi. O lo'o tu'uina atu se faiga moe maualalo e tapuni ai le ta'amilosaga i totonu e ausia ai le fa'ata'ita'iga o lo'o i ai nei, e mafai ona fa'atulaga lenei faiga moe e fa'aaoga ai se pine nSLEEP tuuto.
O lo'o tu'uina atu galuega tapuni i totonu mo le ova, ta'avale pu'upu'u, loka i lalo o le eletise, ma le vevela. O tulaga fa'aletonu e fa'ailoa mai ile pine nFAULT.
