and Functions
. 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 protectio.
