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 chip capacitor.
● 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
