LB11997H
LB11997H is Three-Phase Brushless Motor Driver for CD-ROM Spindle Drive manufactured by SANYO.
Overview
The LB11997H is a 3-phase brushless motor driver especially suited for CD-ROM spindle motor drives.
Package Dimensions unit: mm 3234-HSOP28H-C
[LB11997H]
- 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
