LV8105W中文资料Three-Phase Brushless Motor Predriver for Variable Speed Control数据手册ONSEMI规格书

描述 Description

The LV8105W is a predriver IC designed for variable speed control of 3-phase brushless motors. It can be used to implement a high- and low-side output N-channel power FET drive circuit using a built-in charge pump circuit. High-efficiency drive is possible through the use of low noise PWM drive and synchronous rectifying systems.

特性 Features

• Speed discriminator and PLL speed control system
• Integrated VCO
• Speed lock detection output
• Hall bias switch
• Braking circuit
• Integrated current limiting and lock protection circuits

应用 Application

• Computing & Peripherals
• Multi-Function Printer
