概览

CAT874 是一款开关控制器，通过按钮输入或电话微处理器单元启动/关闭智能手机。CAT874 会监控两个输入，在 PWR_ON 输入处于活动状态（逻辑低电平）之后 或出厂预设最短时间之后输出一个高电平有效输出。在最短超时之前从其活动状态释放输入会将内部计时器复位，并且必须在该计时器重新启动一次新的倒数之前返回活动状态。输出在下一个 PWR_ON 低-高或 VCHG 低-高转换之前将保持高电平。CAT874 的推拉输出能够接收最高 3 mA 的电流。

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.)
