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. The device thus controls the current to
remain under a limit value and prevent rapid heat
generation. This prevents device destruction due to rapid
heating. The absolute maximum voltage rating is 27 V,
and the maximum current is 2.5 A.
Functions and Features
Direct PWM drive (lower side control)
Built-in upper and lower side output diodes
