LB1668M中文资料Motor Driver,Brushless,Two-Phase数据手册ONSEMI规格书

描述 Description

The LB1668M is 2-phase unipolar drive brushless motor driver that feature a wide usable voltage range and a minimal number of required external components. They also support the formation of motor lock protection and automatic recovery circuits.

特性 Features

• Output protection Zener diodes with variable breakdown voltages :When the Z1 and Z2 pins are open : VOLM = 57VWhen the Z1 and Z2 pins are shorted : VOLM = 32VAn external Zener diode can be connected between
• Can support both 12V and 24V power supplies by changing an external resistor.
• Hall elements can be connected directly.
• Built-in rotation detection function that outputs low when driven and high when stopped.
• Motor lock protection and automatic recovery functions built
• Thermal shutdown function.

简介

LB1668M属于集成电路（IC）的全半桥驱动器。由ONSEMI制造生产的LB1668M全半桥驱动器器件属于电桥驱动器电源管理集成电路 (PMIC) 系列，包含两个或多个功率晶体管，以及在外部器件控制下将其用作开关所需的电路。这些晶体管通常在内部配置为成对串联连接（称为半桥），因而任意指定晶体管对之间的结点都可以连接至两个电源轨中的任一个。这类器件常用于将控制器件（如微控制器）提供的低电平信号转换为操作执行器（如步进电机或无刷电机）所需的较大功率信号。
