Part Number: DRV8880
Above sch is the part of the DRV8880 dirve step motor sch , the signal OUT2A1,OUT2A2,OUT2B1,OUT2B2 are from the DRV8880 output IO AOUT1,AOUT2,BOUT1,BOUT2, the right side signal （A1S2,A2S2,B1S2,B2S2) are connect to the output terminal block， the 4pin terminal connect to the 4 wire bipolar step motor, the 5 pin connect to the 5 wrie unipolar step motor(but the com pin will be hang in the air , not connect any signal ).
my question is according the datasheet the DRV8880 is design for bipolar step motor ,how they drive the unipolar step motor as above sch design ?
