ROHM BA6846FV, BA6846FS Datasheet

Motor driver ICs

Stepping motor driver

BA6846FS / BA6846FV

The BA6846FS and BA6846FV are stepping motor drivers with a maximum output current of 0.5A. The logic input allows
three output modes : forward, reverse, and power save. The ICs have low output saturation voltage and are capable
of driving motors at low supply voltage.

Applications
Stepping motors for floppy disk drives
