LB11999H - Three-Phase Brushless Motor Drivers for CD-ROM Spindle Motor Driver (supports 44x / 48x / 50x)

Description

Pin number 3 (26) 4 (25) 6 (22) Pin name VCC2 VCC3 VCC1

( ): LB11999H Equivalent circuit Unit (Resistance: Ω, capacitance: F) Pin function Source side predrive voltage supply pin.

Constant current control amplifier voltage supply pin.

Features

  • Package Dimensions unit: mm.
  • Current linear drive 3227-HSOP24.
  • Control V type amplifier.
  • Separate power supply for output upper side bias circuit allows low output saturation by boosting this 15.3 4.3 power supply only (useful for 5V power supply types). 24.
  • 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 cir.
