Stepper Motor Drivers...

from ROHM Semiconductor...

ROHM Stepper Motor Drivers (SMDs) offer designers a selection of products with the performance features required for printers and copiers, scanners, security cameras, robotics, sewing machines, factory automation and other applications requiring precision motor control. Five product series are offered providing the ability to optimize the combination...

of function, performance, power and package size. Reliable operation is the hallmark of ROHM Stepper Motor Drivers. A built-in voltage regulator in most models eliminates the need for control sequencing during power ON/OFF to prevent circuit malfunctions. ROHM SMDs also incorporate voltage, current and thermal protection circuits not...

typically found in this class of device. Plus, ROHM's exclusive Ghost Supply Prevention function prevents aberrant operation in OFF mode. Finally, ROHM's fabrication process yields products that exhibit exceptional ESD withstand, low ON resistance and low heat generation. The small package sizes are further enhanced by the reduction in external components....
