Ordering number : EN5976A LB1995 Monolithic Digital IC LB1995 Three-Phase Brushless Motor Driver for CD-ROM Spindle Drive Overview The LB1995 is a three-phase brushless motor driver especially suited for CD-ROM spindle motor drives. Package Dimensions unit: mm 3227-HSOP24 [LB1995] 15.3 4.3 0.3 Allowable power dissipation, Pd max – W • Current linear drive • Control V type amplifier with single side control switching pin • 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.
