公司介绍
CAT4002A 提供两个匹配的低漏电流源来驱动 LED。CAT4002A 使用外部电阻 RSET 设置 LED 沟道中的电流。每个 LED 沟道都包含一个单独的控制环路,使得该器件能够处理较宽的 LED 前向电压范围,同时能够保持严格的电流匹配。EN/DIM 逻辑输入支持器件启用和数字调光接口,用于以 32 个线性调光级别设置 LED 沟道电流。由于低漏(50 mV,20 mA)汲电流,LED 可直接从锂离子电池供电。该器件采用 6 引线 TSOT-23 和 SC-70 封装。

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.)
