Motor driver ICs
CD-ROM spindle motor driver
BA6855AFM
The BA6855AFM is a CD-ROM motor driver with a built-in motor power supply switching
regulator.
The switching
regulator allows low-power designs, and reduced thermal dissipation from the IC.
It is possible to select reverse brake and short brake modes.
FApplications CD-ROM, CD-R, CD-RW, DVD-ROM, and DVD-RAM FFeatures 1) Motor switching
regulator on chip.
2) Selectable brake mode via BR pin.
3) FG signal output also possible at power save via FGS.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
