„ Overview
The AN41204A optical disc motor drive IC incorporates a
1-channel 3-phase full-wave PWM motor driver featuring
low vibration and noise as well as a 5-channel PWM output
driver for linear input. 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.
