LB11975 Description
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...
