LB11996H - Three-Phase Brushless Motor Driver for CD-ROM Spindle Motor Driver
Pin number 3 (26) 4 (25) 6 (22) Pin name VCC2 VCC3 VCC1 ( ): LB11996H, other pins: identical Equivalent circuit Unit (resistance: Ω) Pin function Source side predrive voltage supply pin.
Constant current control amplifier voltage supply pin.
Power supply pin for all voltage except output transistors
LB11996H 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
