Details
OverviewThe 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• Supports the use 3.3 V DSP devices.• Power saving function for standby mode• Hall FG output (1 or 3 Hall device operation)• Built-in Hall device power supply• Reverse rotation detection output and drive cutoff circuit• Voltage control amplifier• Current limiter circuit• Thermal protection circuit
