ROHM BD63800MUF-CE2, Stepper Motor Driver IC

The ROHM stepping motor driver is driven by PWM current. Rated power supply voltage of the device is 40 V, and rated output current is 1.35 A. It has two input interface as driving mode(CLK-IN and SPI-IN), and six excitation modes(full step, 1/2, 1/4, 1/8, 1/16 and 1/32 step). It has mix decay mode(the seamless adjustment function of slow/fast decay ratio), and auto decay mode(automatic switching function of slow/fast decay), can realize the optimized control status for all kinds of motor. In addition, it operates with single power supply which can simplify the set design. It has under voltage motor hold, open detection, stall detection functions.
