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)

FOperation notes
(1) FGS
When a high-level voltage is input to FGS, the FG output
is output even when power save is on (PS = low level).
Also, the Hall bias terminal stays in the operating state.
(2) Switching regulator
The BA6855AFM has a switching regulator pin.
The IC has an oscillator circuit, and the output is
compared to the low-level voltage detector output and
output on VREG.
