♠ DRV8824 Stepper Motor Controller IC
DRV8824 e fana ka tharollo e kopaneng ea mokhanni oa makoloi bakeng sa lihatisi, li-scanner, le lisebelisoa tse ling tse ikemetseng. Sesebelisoa sena se na le bakhanni ba babeli ba borokho ba H le indexer ea microstepping, 'me e reretsoe ho khanna koloi ea bipolar stepper. Sebaka sa ho khanna se hlahisoang se na le li-MOSFET tsa matla a N-channel tse hlophisitsoeng joalo ka marokho a H a felletseng a ho khanna maqhubu a enjene. DRV8824 e khona ho khanna ho fihla ho 1.6 A ea hona joale ho tsoa ho sehlahisoa se seng le se seng (ka heatsinking e nepahetseng, ho 24 V le 25 ° C).
Sehokelo se bonolo sa STEP/DIR se lumella ho hokahana habonolo ho lipotoloho tsa taolo. Li-mode pins li lumella ho hlophisoa ha enjene ka mehato e felletseng ho isa ho 1/32-step modes. Mokhoa oa ho bola o ka lokisoa e le hore ho ka sebelisoa ho bola butle, ho bola ka potlako, kapa ho bola ho tsoakiloeng. Ho fanoe ka mokhoa oa ho robala o nang le matla a fokolang a koalang potoloho ea ka hare ho fumana mokhoa oa ho robala o tlaase haholo. Mokhoa ona oa ho robala o ka hlophisoa ho sebelisoa pini e inehetseng ea nSLEEP.
Ts'ebetso ea ho koala ha ka hare e fanoa bakeng sa overcurrent, short circuit, undervoltage lockout, le mocheso o fetang. Maemo a phoso a bontšoa ka pini ea nFAULT.
