LV8068V数据手册集成电路（IC）的全半桥驱动器规格书PDF

描述 Description

The LV8068V is single-phase bipolar fan motor is driven, through BTL output linear driver, at high efficiency, low power, and low noise by suppressing the reactive power. The BTL output can put PWM control by an outside signal together, which is optimum for the CPU cooler, etc.

特性 Features

• Single-phase full-wave operating by BTL output (BTL amplifier gain : +49dB)
• Speed control available by PWM input
• The characteristic of the motor rotational speed adjust by VCONT voltage
• The characteristic of the motor rotational minimum speed adjust by RMI voltage
• Hall bias output terminal (VHB = 1.32V (typ))
• Built-in Quick Start circuit
• Startup support function (50% Duty Start)
• FG (rotate detection) output terminal (Open drain output)
• RD (Lock detection) output terminal (Open drain output)
• Built-in Current Limiter circuit (limit at IO = 250mA with Rf = 1 connection, the limiter value determined with Rf.)
• Built-in lock protection and automatic return circuit
• Built-in thermal shut-down (TSD) circuit

简介

LV8068V属于集成电路（IC）的全半桥驱动器。由制造生产的LV8068V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。
