µ-step,36V Series Stepper Motor Drivers - BD63847EFV
ROHM's 36V micro-step motor driver was designed to improve torque while decreasing noise at high speeds. 1/16-step driving is possible via CLK signal input and the excitation mode selection and for current decay mode, the ratio of FAST DECAY & SLOW DECAY can be freely set. So the optimum conditions for every motor can be realized.
