4.5 - 5.5v Disk Driver Spindle & Vcm, Power & Control Combo??s

The L6260 is single chip sensorless (DC) spindle motor and voice coil controllers including power stages suitable for use in small disk drives. These devices have a serial Interface for a micro- processor 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 Fre- quency Locked Loop (F.L.L.). No external compo- nents 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 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 BICMOS technology al- lowing dense digital circuitry to be combined with MOSBipolar power devices. By STMicroelectronics
