供应 NUD4700SNT1G 电源监控芯片

NUD4700SNT1G

The NUD4700 is an electronic shunt which provides a current bypass in the case of a single LED going into open circuit. LEDs are by nature quite fragile when subjected to transients and surge conditions. There are also many cases where high reliability of the LED lighting must be maintained such as headlights, lighthouses, bridges, aircraft, runways and so forth. In these cases the low cost addition of the NUD4700 will provide full assurance that an entire string of LEDs will not extinguish should one LED fail. NUD4700 is also applicable to other loads where circuit continuity is required. This device is designed to be used with 1 W LEDs (nominally 350 mA @ 3 V).

Features

• A Simple Two Terminal Device 

• Automatically Resets Itself if the LED Heals Itself or is Replaced 

• ON−State Voltage Typically 1 V 

• OFF−State Current less than 250 A 

• Available with White Package 

• SZ Prefix (black package only) for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q101 Qualified and PPAP Capable 

• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant

NUD4700是一个提供电流旁路的电子分流器，如果单个LED出现断路。LED是天生的在瞬态和浪涌条件下非常脆弱。在那里也有许多情况下，高可靠性的LED照明必须得到保证
如头灯、灯塔、桥梁、飞机、跑道等等等。在这些情况下，NUD4700的低成本添加将确保整个LED灯串不会熄灭如果一个LED出现故障。NUD4700也适用于其他负载要求电路导通性。本设备设计用于

1 W LED（标称350 mA@3 V）。
