LB11995H

Three-Phase Brushless Motor Driver

for CD-ROM Spindle Drive

Monolithic Digital IC

The LB11995H is a 3-phase brushless motor driver

especially suited for CD-ROM spindle motor drives.

Functions

• 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.

• Built-in short braking circuit

• Built-in reverse blocking circuit

• Hall FG output

• Built-in S/S function

• Built-in current limiter circuit (selectable, 2 steps)

• Built-in Hall power supply

• Built-in thermal shutdown circuit

• Supports 3.3V DSP
