LB1860M Datasheet Two-phase Half-wave Variable Speed Fan Motor Driver

Manufacturer: onsemi

Overview: LB1860, LB1860M, LB1861, LB1861M Monolithic Digital IC Two-Phase Half-Wave Variable Speed Fan Motor Driver Overview The LB1860 series ICs are drivers for two-phase unipolar drive DC brushless fan motors. They have functions such as driving, lock protection, restart and speed control.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.
