NCP459中文资料负载开关数据手册ONSEMI规格书

描述 Description

NCP458 is power load switch with very low Ron NMOSFET controlled by external logic pin, allowing optimization of battery life, and portable device autonomy.
Indeed, thanks to a best in class current consumption optimization with NMOS structure, leakage currents are drastically decreased. Offering optimized leakages isolation on the ICs connected on the battery .
Output discharge path is proposed, in the NCP459 version , to eliminate residual voltages on the external components connected on output pin.
Reverse voltage protection, from OUT to IN is offered in the NCP458R version.
Proposed in wide input voltage range from 0.75 V to 5.5 V, and a very small CSP8 1 x 2 mm

特性 Features

• Very Low IQ
• Saves Battery life time
• Ultra Low Rdson
• Allows 4.5 A DC current

应用 Application

• Switch Power Supply rail to save leakage current
• Notebook Computers
• Tablets / Fablets
• Mobile / Smart Phones
• Digital Camera

简介

NCP459属于开发板套件编程器的评估演示板及套件。由ONSEMI制造生产的NCP459评估和演示板及套件该系列产品提供了一种方便的方法，在经过验证的实施环境中评估某些重点器件的性能或特性。评估方法通常有完善的文档说明，并且视乎具体情况由评估软件提供支持。产品通常由印刷电路板组成，板上已装有重点器件以及必要或有用的支持元器件，另外也可能包括其他组件，例如电缆或电源。对于数量特别多或类别独特的器件类别(如 ADC、DAC 和开关模式电源)，评估平台可组合为一个单独的产品系列。
