DESCRIPTION
The L6260 is single chip sensorless (DC) spindle
motor and voice coil controllers including power
stages suitablefor use in small disk drives.
These devices have a serial interface for a micro-
processorrunning up to 10 Mega bits per second.
There are registers on chip to allow the setting of
the desired spindle speed via the on chip Fre-
quencyLocked Loop (F.L.L.). No external compo-
nents are requiredin the sensor-less operation as
the control functions are integrated on chip (e.g.
B.E.M.F. processing, digital masking, digital delay
and sequencing).
The V.C.M. drivers uses a transconductanceam-
plifier, able to provide 2 different current ranges,
suitable for seeking and tracking.
When a low voltage is detected,a Power On Re-
set (P.O.R.) is issued and the internal registers
are reset, the spindle power circuitry is tri-stated,
B.E.M.F. synchronous rectification is enabled, the
actuator retracts and then dynamic braking of the
spindle is applied.
These devices are built in BICMOStechnologyal-
lowing dense digital circuitry to be combined with
MOS\Bipolarpower devices.
