Motor Controller suits 1.8 and sub-1.8 in. hard disk drives.(Highly-Integrated Hard-Disk-Drive Motor Controller Chip from STMicroelectronics Maximizes Battery Life in Portable Consumer Electronics Products)

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.
