ROHM Semiconductor BD63910MUV Stepper Motor Driver

ROHM Semiconductor BD63910MUV Stepper Motor Driver is a bipolar low-consumption driver that is driven by a PWM current. This motor driver operates at 36V rated supply voltage and 1A rated output current. The BD63910MUV motor driver adopts CLK-IN and PARA-IN driving mode for the input interface. This motor driver includes full (two kinds)-, half (three kinds)-, quarter (two kinds)-, 1/8-, and 1/16-step modes. The BD63910MUV motor driver from ROHM Semiconductor features the current decay mode switch with the linearly variable FAST/SLOW DECAY ratio. This motor driver incorporates the normal rotation and reverse rotation switching functions. Typical applications include PPC, multi-function printers, laser beam printers, ink-jet printers, monitoring cameras, WEB cameras, sewing machines, photo printers, FAX, scanners, and mini printers.
