ROHM BD63860EFV-E2, Stepper Motor Driver IC

BD63860EFV has the 3-bit DAC, and is designed to operate bipolar stepper motors in eighth-step modes. As for its basic function, it is a low power consumption bipolar PWM constant current-drive driver with power supply's rated voltage of 36V and rated output current of 2.5A peak. For the input interface, the CLK-IN drive mode. There are excitation modes of FULL STEP, HALF STEP, QUATER STEP and EIGHTH STEP mode, and for current decay mode, the ratio of FAST DECAY & SLOW DECAY can be freely set, so the optimum control conditions for every motor can be realized.
