CAT5419 是与控制逻辑和 16 字节的 NVRAM 内存集成的两个数字 POT。一个单独的 6 位控制寄存器 (WCR) 独立控制每个数字 POT 的弧刷抽头位置。与每个弧刷控制寄存器相关联的是四个 6 位非易失性内存数据寄存器 (DR),用于存储最多四个弧刷设置。通过 2 线串行总线(类似 I²C)写入弧刷控制寄存器或任何非易失性数据寄存器。加电时,两个电位计中的每个电位计的第一个数据寄存器 (DR0) 的内容将自动加载到其各自的抽头控制寄存器 (WCR) 中。写保护 (WP) 引脚可防止对数据寄存器意外编程。CAT5419 可用作电位计或双端可变电阻器。它适用于各种应用中的电路电平或系统电平调整。

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.)
