Optical Disc Motor Drive IC AN41204A
„ 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.
