Integrating all circuits needed to control and drive HDD spindle motor and voice coil actuator, Model L7208 HDD is intended for portable consumer electronics. Smooth Drive[R] pseudo-sinusoidal digital-drive technology minimizes acoustic noise from spindle motor. Class AB output stage has zero dead-band and minimal crossover distortion, and power FETs deliver up to 0.5 A peak current. Controller connects to host system through serial bus running at up to 50 MHz.
Ultra-thin hard-disk-drive Motor Controller integrates all necessary power FETs and is optimized for 1.8-inch and sub-1.8-inch consumer equipment drives
