LB1860M集成电路（IC）的电机驱动器控制器规格书PDF中文资料

LB1860M属于集成电路（IC）的电机驱动器控制器。由安森美半导体制造生产的LB1860M电机驱动器，控制器产品属于电机驱动器和控制器电源管理集成电路 (PMIC) 系列，可用于控制或操作从某电源施加到电机或相关机电执行器的电源。所实现的具体功能和特性集根据预期负载和预期应用的特性有很大差异，范围从用于有刷电机的简单开环速度控制到基于步进电机的高级闭环运动控制。

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
