LB11867RV - Variable Speed Single-phase Full-wave Pre-driver

Features

  • Single-phase full-wave driving pre-driver ⇒ Low-saturation drive using external PMOS-NMOS enables high-efficiency low power-consumption drive.
  • Variable speed control possible with external PWM input ⇒ Separately-excited upper direct PWM (f =30kHz) control method ensures highly silent speed control.
  • Current limiting circuit incorporated ⇒ Chopper type current limiting made at startup and during lock.
  • Reactive current cut circuit incorporated ⇒ Reactive cur.
