FAN8841 是一款由步升 DC-DC 转换器组成的单芯片压电驱动器,集成了 36 V 升压开关和双半桥输出级。该步升 DC-DC 转换器在临界导通模式 (CRM) 下运行,可降低 DC-DC 转换器的开关损耗,实现高能效。它经过了优化,可在耦合电感配置中运行,提供 60 V 以上的输出电压。该步升 DC-DC 转换器具有软启动功能,可限制启动期间的涌入电流。包括了过电压保护和过电流保护。过电压保护用于在步升 DC-DC 转换器输出电压低于指定的阈值电压时禁用该双半桥门极驱动器。升压使用 VCON 引脚处的外部电阻和模拟电压进行设置,步升电流限值可通过 OCP 引脚处的外部电阻进行编程。输出半桥集成了 75 V P 和 N 沟道,用于压电驱动。开漏故障输出 (FO) 信号指示是否发生了异常过电压。

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.)
