概览

ADM1023 是一款两沟道数字温度计和温度过低/过高报警器，适用于需要热监控和热管理的个人电脑和其他系统。该器件提供的更高准确度针对 Pentium® III 而优化，让系统设计人员能够安全降低温度保护带，提高系统性能。该器件可以使用 Pentium III 或类似处理器片上附带的二极管联接 PNP 晶体管测量微处理器的温度；也可以是低成本的分立 NPN/PNP 器件，如 2N3904/2N3906。新型测量技术消除了晶体管基极-射极电压的绝对值，因此不需要校准。第二个测量沟道测量片上温度传感器的输出以监测该器件及其环境的温度。

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.)
