2-phase Stepping Motor Driver

SANYO -> Panasonic 

• Motor current peak value IOH setting

STK672-740B-E

IOH

0

IOH=(Vref÷4.9) ÷Rs

The value of 4.9 in Equation above represents the Vref voltage as divided by a circuit inside the control IC.

Vref=(R02÷ (R01+R02)) ×5V(or 3.3V)

Rs is an internal current detection resistor value of the hybrid IC.

Rs=0.089Ω when using the STK672-740B-E
