LA6503 - CD-ROM Drive Spindle Motor Driver + Sled Motor Driver + Sled Motion/Position Detector IC

Key Features

  • CAV control spindle motor driver.
  • Three-phase brushless motor driver.
  • IOmax = 1 A.
  • Built-in FG output circuit (single Hall detection output).
  • Reverse braking circuit.
  • Built-in start/stop circuit.
  • Upper side current detection for minimal loss in the current detection resistor. Also, the voltage drop in this resistor reduces the IC internal power dissipation.
  • Built-in thermal shutdown circuit.
  • Sled motor driver.
