Eigenschaften:

• The hall sensor is not needed by 3-phase sensor less drive system.
• The spindle motor driver achieves stability high speed start by ROHM's own energizing method.
• Spindle, stepping and SA stepping achieve high efficiency drive by PWM control driver.
  The actuator is able to reduce power consumption by using PWM drive system.
• The loading adopts forward/reverse-rotation drive system.
• ON/OFF of loading and other channels, brake mode of spindle driver, and stand-by mode are selectable by the two control terminals.
• Built-in thermal-shut down circuit.
• Improved heat radiation efficiency utilizing lm-type HTSSOP package with good thermal conductivity.
