LB11975 - High-Speed CD-ROM Spindle Motor Driver IC
Ordering number : ENN6497A Monolithic Digital IC LB11975 High-Speed CD-ROM Spindle Motor Driver IC Overview The LB11975 is a monolithic bipolar IC developed for uses as a spindle motor driver for high-speed CD-ROM and DVD-ROM drives.
To minimize heat generation during high-speed rotation and braking, the LB11975 adopts direct PWM drive in the output stage.
During reverse braking the upper and lower side output transistors are both driven in PWM mode to implement dual PWM controlled braking.
