概览

NCP339A 和 NCP339B 为极低导通电阻 MOSFET，通过外部逻辑引脚控制，可优化电池寿命和便携式设备自主性。实际上，由于采用了 PMOS 结构实现电流消耗优化，当不使用电池时，通过隔离电池上连接的集成电路可以消除漏电流。如果 OUT 引脚电压高于 IN 引脚电压，则会自动进行反向阻断控制，从而消除了从 OUT 引脚到 IN 引脚的漏电流。禁用器件时，NCP339B 可提供输出自动放电功能。

Re-calculate Data

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.)
