LV8161MU中文资料Single-Phase Fan Motor Driver数据手册ONSEMI规格书

描述 Description

LV8161MU is the driver IC with BTL linear output for single-phase fan motor, and that drives at low noise by suppressing the reactive power. Moreover, it has the function to fix to the rotational speed corresponding to the oscillatory frequency set with CIN/COUT pins, and that speed control is done by PWM. So, the output signal forms BTL combined with PWM.It is optimum for the small fan motor that requires low power dissipation, low noise, and the fixed rotational speed.

特性 Features

• Single-phase full wave operating by BTL output(BTL amplifier gain: +45.5dB)
• The fixed rotational speed function(possible to adjust the speed by the value of resistor and capacitor connected to CIN/COUT pins)
• Hall bias output pin (VHB = 1.03V (typ))
• FG (rotation signal) output pin (Open drain output)
• Built-in motor start-up assistance function(PWM with 100% duty in output at start-up)
• Built-in lock protection and automatic restart circuit
• Built-in thermal-shutdown (TSD) circuit

简介

LV8161MU属于集成电路（IC）的全半桥驱动器。由制造生产的LV8161MU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。
