Monolithic Digital IC
LB11999,11999H
Three-Phase Brushless Motor Drivers
for CD-ROM Spindle Motor Driver (supports 44×, 48×, 50×)
Features
Package Dimensions
• Current linear drive
• Control V type amplifier
unit: mm
3227-HSOP24
• 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 loses loss

Pin function
GND pin for all circuits except output.
Control loop frequency compensator
pin.
Connecting a capacitor between this
pin and GND prevents closed loop
oscillation in current limiting circuitry.

collector pin (common for all 3
phases).
For current detection, connect
resistor between VCC3 pin and RF
pin. Constant current control and
current limiter works by detecting this
voltage.
