By Technology
CAT9532 是一个 CMOS 器件,提供用于 LED 调光控制的 16 位并行输入/输出扩展器。CAT9532 输出可以直接驱动 16 个并联 LED。每个 LED 均可单独开关或以两个可编程速率之一进行闪烁。该器件为背景灯或色彩混合应用提供了 256 个亮度梯度的 LED 调光简单方案。CAT9532 适用于兼容 I2C 和 SMBus 且必需限制总线数据量或释放主总线计时器的应用。 CAT9532 包含一个内部振荡器和两个 PWM 信号,用于驱动 LED 输出。用户可以为每个 PWM 信号编程时段和占空比。发出初始设置命令来编程闪烁速率 1 和闪烁速率 2(频率和占空比)之后,仅需主总线的一个命令即可打开、关闭每个开漏输出或以闪烁速率 1 和闪烁速率 2 循环。 每个开漏 LED 输出均可提供 25 mA 的最大输出电流。所有 I/O 接收的总电流不得超过 200 mA。

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.)
