Overview
The LB1995 is a three-phase brushless motor driver especially suited for CD-ROM spindle motor drives.

Functions
• 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.
• Built-in short braking circuit
• Built-in reverse blocking circuit
• Hall FG output
• Built-in S/S function
• Built-in current limiter circuit
• Built-in Hall power supply
• Built-in thermal shutdown circuit
