Key Features

  • Two-speed mode select function requiring less external component additions : Full speed and Low speed. Or, thermistor-controlled continuous variable-speed function according to ambient operation temperatures. Motor starts rotating at a low speed.
  • Motor lock protection and automatic return circuit built in.
  • Output transistors: Output current IO = 1.5 A, output circuit protection Zener diodes (LB1860 : M-Vz = 57 V/ LB1861: M-Vz = 32 V) Enables low-level noise protection with c.
