DRV8847 Dual H-Bridge Motor Driver
Sesebelisoa sa DRV8847 ke mokhanni oa likoloi tse peli tsa H-borokho bakeng sa lits'ebetso tsa indasteri, lisebelisoa tsa lapeng, liprinta tsa ePOS, le lisebelisoa tse ling tsa mechatronic. Sesebelisoa sena se ka sebelisoa ho khanna li-motor tse peli tsa DC, enjene ea bipolar stepper, kapa meroalo e meng e joalo ka li-relay. Sebopeho se bonolo sa PWM se lumella sebopeho se bonolo le molaoli. Sesebelisoa sa DRV8847 se sebetsa ka matla a le mong mme se ts'ehetsa phepelo e pharalletseng ea phepelo ho tloha ho 2.7 ho isa ho 18 V.
Mokhahlelo oa tlhahiso ea mokhanni o na le li-MOSFET tsa matla a N-channel tse hlophisitsoeng e le marokho a mabeli a H a tletseng a ho khanna li-motor windings kapa marokho a mabeli a ikemetseng (ka sebopeho se ikemetseng sa borokho). Nako e tsitsitseng e laola tlhōrō ea hona joale borokhong e ka khanna mojaro oa 1-A (2-A ka mokhoa o ts'oanang le mocheso o nepahetseng oa mocheso, ho 25 ° C TA).
Ho fanoa ka mokhoa oa ho robala o nang le matla a tlase ho fumana sebaka se tlase se khutsitseng ka ho koala boholo ba potoloho ea kahare. Ho feta moo, ho fanoa ka torque scalar e lekanyang tlhahiso ea hona joale ka pini ea ho kenya ea dijithale. Karolo ena e lumella molaoli ho fokotsa nako e hlokahalang bakeng sa tšebeliso e tlase ea matla.
Mesebetsi ea ts'ireletso ea ka hare e fanoa bakeng sa undervoltage-lockout, ts'ireletso ea overcurrent ho FET ka 'ngoe, ts'ireletso ea potoloho e khutšoanyane, ho lemoha mojaro o bulehileng, le mocheso o feteletseng. Maemo a phoso a bontšoa ke pineng ea nFAULT. Mofuta oa sesebelisoa sa I 2C (DRV8847S) o na le tlhahlobo e felletseng.
