Integrating a spindle driver and channel driver on a single chip and using small, thin packaging reduces the mounting area. This helps to develop equipment that is more compact, slim and lightweight. „Feature

• All-channel PWM driving power consumption is among the lowest of its kind.
• Low-vibration and low-noise sinewave PWM is used to drive the spindle section.
• Dead zone-less PWM driving for focus, tracking and tilt.
• Stepper motor drivers on two channels.
• Built-in thermal shutdown function.
• Compact, slim package. „Applications Slim DVD recording units (RAM/+RW/-RW), optical disc units such as slim combination drives and car navigation systems. Achieving a 1-chip motor drive.
