LB1860-E中文资料安森美半导体数据手册PDF规格书

特性 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 power supply by changing an external resistor. (Strong protection against power supply surge)

• Connectable direct to a Hall element
