NCP331中文资料Soft Start Controlled Load Switch with auto discharge数据手册ONSEMI规格书

描述 Description

The NCP331 is a low Ron N-channel MOSFET controlled by a soft start sequence of 1.5ms for mobile applications.
The very low Rdson allows system supplying or battery charging up to DC 3A.The device is enable automatically if a Power Supply is connected on Vin pin (active High) and maintained off if no Vin (internal pull down).
Thanks to a current consumption optimization, leakage current is drastically decreased from the battery connected to the device, allowing long battery life.

特性 Features

• 1.8 V – 5.5 V operating range
• DC current up to 3 A
• Output discharge option
• Eliminates residual voltage on the output rail

应用 Application

• Load Management
• Tablets
• Digital Cameras
• GPS
• Computers

简介
