SANYO LB11999, LB11999H Datasheet

Ordering number : ENN6180

for CD-ROM Spindle Motor Driver (supports 44×, 48×, 50×)

LB11999,11999H

Monolithic Digital IC

LB11999,11999H

Three-Phase Brushless Motor Drivers

Features

• 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 loses 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
