Ordering number : ENN*6231 LB11997H Monolithic Digital IC LB11997H Three-Phase Brushless Motor Driver for CD-ROM Spindle Drive Preliminary Overview The LB11997H is a 3-phase brushless motor driver especially suited for CD-ROM spindle motor drives. Package Dimensions unit: mm 3234-HSOP28H-C [LB11997H] 15.3 28 15 • Current linear drive • Control V type amplifier • Separate power supply for output upper side bias circuit allows low output saturation by boosting this power supply only (useful for 5V power supply types). • Upper side current detection technique reduces loss voltage of current detection resistor. Voltage drop caused by this resistor reduces internal power dissipation of IC.
