LB11660RV - Single-Phase Full-Wave Driver

Features

  • Single-phase full-wave drive (15V-1.5A output transistor built in) upper output Tr incorporated half pre-driver.
  • Variable speed control by an external signal. →Separately-excited upper TR direct PWM control method, enabling silent, low-vibration variable speed control.
  • Lowest speed setting possible.
  • Current limiter circuit (the circuit actuated at IO = 1A when Rf = 0.5Ω, Rf determines the limiter value. ).
  • Kickback absorption circuit built in.
