Preliminary

LB11996,11996H

Monolithic Digital IC

LB11996,11996H

Three-Phase Brushless Motor Driver

for CD-ROM Spindle Motor Driver

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

• Built-in Hall power supply

• Built-in thermal shutdown circuit

• 1 Hall FG/3 Hall FG switchable

• Supports 3.3V DSP
