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 felletseng a H-ho khanna li-motor windings kapa marokho a ikemetseng a halofo (ka sebopeho se ikemetseng sa borokho).Nako e tsitsitseng e laola tlhōrō ea hona joale borokhong e ka tsamaisang mojaro oa 1-A (2-A ka mokhoa o ts'oanang le mocheso o nepahetseng oa mocheso, ho 25 ° C TA).
