L6260 General Description
The L6260 is single chip sensorless (DC) spindle motor and voice coil controllers including power stage s suitable for use in small disk drives. These devices have a serial interface for a microprocessor running 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 Frequency Locked Loop (F.L.L.). No external components are required in 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 transconductanceamplifier, able to provide 2 different current ranges, suitable for seeking and tracking.
When a low voltage is detected, a Power On Reset (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 BICMOS technology allowing dense digital circuitry to be combined with MOS\Bipolar power devices.
