The BA6845FS is a stepping motor driver with a maximum output current of 1.0A. The logic input allows three output
modes : forward, reverse, and power save. The IC has a low output saturation voltage and is capable of driving motors
at low supply voltage.
FApplications
Stepping motors for floppy disk drives
FFeatures
1) Low output saturation voltage.
2) Power save circuit.
3) Thermal shutdown circuit.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
