概览

FAN54120是一款兼容USB的单节电池锂离子电池的线性充电器，具有电能回馈（Power Back）功能，支持死电池恢复、预充电、快速充电和浮充。快速充电电流（IFAST）由外部电阻器设置。预充电（IPRE）和充电完成（ICHGEND）电流在出厂时分别设置为IFAST/5.2和IFAST/10。开漏（“STAT”）引脚提供充电和/或故障状态提示。 “Power Back”功能可以使电池为配件供电。

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.)
