概览

NCT214 是一款双沟道数字式温度计和低温/高温警报器，适用于 PC 和热管理系统。它可与 ADM1032 和 ADT7461 实现寄存器兼容。NCT214 具有串联电阻抑制功能，可从温度结果中自动消除温度监控二极管高达 1.5 kΩ（典型值）的串联电阻，从而滤除噪声。NCT214 有一个可配置的 /ALERT 输出，以及可切换的宽广温度测量范围。NCT214 的远程热二极管温度测量准确度为 ±1°C，环境温度测量准确度为 ±3°C。温度测量范围默认为 0°C 至 +127°C，与 ADM1032 兼容，但它可以切换为更宽的测量范围 -64°C 至 +191°C。NCT214 通过 2 线串行接口进行通信，符合系统管理总线 (SMBus/I2C) 标准。NCT214 具有两个地址引脚，最多可允许同一个总线上使用 9 个 NCT214。当片上或远程温度超出范围时，/ALERT 输出会发出信号。/THERM 输出是一个比较器输出，可以控制冷却风扇的开关。如果需要，可以将 /ALERT 输出重新配置为次级 /THERM 输出。

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.)
