L7200

The L7200 Mozart integrates into a single chip both spindle and VCM controllers as well as power stages. The L7200 is designed for 12V disk drive application requiring up to 2.5A of spindle and 1.7A of VCM peak currents. The L7200 is based on the sinusoidal driving of the spindle motor. This is realized digitally by the SMOOTHDRIVE™ SYSTEM.

A serial port with up to 40 MHz capability provides easy interface to the microprocessor. A register controlled Frequency Locked Loop (FLL) allows flexibility in setting the spindle speed. Integrated BEMF processing, digital filter, digital masking, digital delay, and sequencing minimize the number of external components required.
