Optical Disc Motor Drive IC AN41204A Overview Unit : mm 9.00±0.20 7.00±0.10 (4.20) (3.37) Area of no resin flash 36 25 37 7.00±0.10 9.00±0.20 (0.75) 24 (3.37) 13 48 1 0.50 (0.75) 0.20±0.05 0.10 M +0.10 • 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. 12 0.15±0.05 SEATING PLANE (1.00) (1.00) Feature 0.10 –0.05 1.20 max (4.20) 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. 0.10 0˚ to 8˚ 0.50±0.10 HQFP048-P-0707 Applications Slim DVD recording units (RAM/+RW/-RW), optical disc units such as slim combination drives and car navigation systems.
