SANYO LB11996, LB11996H Datasheet
Ordering number : ENN*6181A
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
