Ordering number : EN5978A LB1997 Monolithic Digital IC LB1997 Three-Phase Brushless Motor Driver for CD-ROM Spindle Drive Overview The LB1997 is a three-phase brushless motor driver especially suited for CD-ROM spindle motor drives. Package Dimensions unit: mm 3222-HSOP28 [LB1997] 28 15 Functions 5.6 1.0 0.2 Allowable power dissipation, Pd max – W • 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 effect of this resistor reduces internal current drain of IC.
