概览

NCP347 能够在检测到错误输入运行情况时将系统从其输出引脚断开。 该系统受高达 +28 V 的正向过电压保护。由于此器件使用内部 NMOS，无需外部器件，降低了系统成本和应用主板中的 PCB 面积。由于集成的低导通电阻功率 NMOS （65 mΩ，如果输入电压超过过电压阈值（5.63 、5.9 或 7.2 V），或 2.95 V (UVLO) 欠电压阈值），NCP347 能够瞬时将输出与输入断开。通电时（EN(BAR) 引脚 = 低电平），Vout 会在 Vin 超过欠电压阈值之后导通 50 ms。NCP347 提供负向转换标志 (FLAG(BAR)) 输出，会在发生故障时警告系统。另外，当使用 1.0 µF 或更大电容器进行旁路联接时，该器件还具有 ESD 保护输入 (15 kV Air)。

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
