By Technology
CAT4109 是一款 3 沟道,恒定电流 LED 驱动器,无需电感器。高达 175 mA 的 LED 沟道电流通过单独的外部电阻进行独立编程。175 mA 时 0.4 V 的低输出电压运行可在多种供电电压范围内实现功效更佳的设计。三个 LED 引脚可兼容最高 25 V 的高电压,支持带有多个 LED 串联的应用。 三个单独控制输入 PWM1、PWM2、PWM3 分别控制 LED1、LED2、LED3 沟道。该器件还包括一个输出启用 (OE) 控制引脚,禁用所有三个沟道,而无论 PWMx 输入状态如何。 该器件结合了高温关断保护,可在片温度超过 150°C 时禁用 LED 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.)
