概览

NCV7693 器件用于驱动多个外部开关组件，以实现 3 个独立功能。每个 LED 串的平均电流可使用正确选择的占空比和电池电压进行调节。此器件的目标应用为汽车尾灯组合。每个驱动器都具有自己的诊断，可检测开路负载、短路接地或短路电池。LED 平均亮度使用合适的占空比以及与双极晶体管串行联接的外部电阻进行轻松编程。多个串联 LED 组可使用一个 NCV7693 器件运行。该器件采用 TSSOP−14 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.)
