Product News Achieving a 1-chip motor drive. 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. 36 37 9.00±0.20 7.00±0.10 (4.20) (3.37) Unit : mm Area of no resin flash 25 24 (0.75) 7.00±0.10 9.00±0.20 (4.20) (3.37) (1.00) 1.20 max +0.10 –0.05 0.10 „ 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.
