Ordering number : ENN6180 LB11999,11999H Monolithic Digital IC LB11999,11999H Three-Phase Brushless Motor Drivers for CD-ROM Spindle Motor Driver (supports 44×, 48×, 50×) Features Package Dimensions unit: mm Current linear drive 3227-HSOP24 Control V type amplifier Separate power supply for output upper side bias circuit allows low output saturation by boosting this 15.3 4.3 power supply only (useful for 5V power supply types). 24 Upper side current detection technique loses loss voltage of current detection resistor. Voltage drop caused by this resistor reduces internal power dissipation of IC.
