LB11867FV中文资料Variable Speed Single-Phase Full-Wave Pre-Driver数据手册ONSEMI规格书

描述 Description

LB11867FV is a single-phase bipolar driving motor pre-driver with the variable speed function compatible with external PWM signal. With a few external parts, a highly-efficient and highly-silent variable drive fan motor with low power consumption can be achieved. This product is best suited for driving of the server requiring large air flow and large current and the fan motor of consumer appliances.

特性 Features

• Low-saturation drive using external PMOS-NMOS enables high-efficiency low power-consumption drive
• Variable speed control possible with external PWM input
• Separately-excited upper direct PWM (f =30kHz) control method ensures highly silent speed control
• Current limiting circuit incorporated
• Chopper type current limiting made at startup and during lock
• Reactive current cut circuit incorporated
• Reactive current before phase changeover is cut, ensuring highly silent and low power-consumption drive
• Minimum speed setting pin
• Minimum speed setting
• Soft start setting pin
• Soft start setting
• Lock protection and automatic reset circuits incorporated
• Lock protection
• FG (rotation speed detection) output
• Easy Speed control
• Thermal shutdown circuit incorporated
• Thermal protection

应用 Application

• Computing & Peripherals
• Industrial
• Server
• Vending Machine
