LB1861M-W-AH Datasheet PDF - ON Semiconductor

●The LB1860 series ICs are driver IC for two-phase unipolar drive DC brushless fan motors. They have functions such as driving, lock protection, restart and speed control.

●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 lock protection and automatic return circuit built in

● Output transistors: Output current IO = 1.5 A, output circuit protection Zener diodes

● Built-in thermal shutdown circuit

● Built-in rotation detect function (Drive mode: L, Stop mode: H)

● The LB1860 series can be operated from either 12 V or 24 V power supply by changing an external resistor. (Strong protection against power supply surge)

● Connectable direct to a Hall element
