.

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
