• 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.

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.

Note)1: Ta = 25°C except storage temperature and operating ambient temperature.
2: Make sure that channels 1 to 5 do not have a current flow exceeding 1000 mA.
3: Power dissipation shows the value of only package at Ta = 85°C.
4: The above drive output current (± 3000 mA) is permissible for a period exceeding 1 ms.
Note) Do not apply current or voltage from outside to any pin not listed above other than power supply and ground pin.
In the current circuit, (+) means current flowing into IC and (-) means current flowing out of IC.
