概览

LC709204F是一款用于 1 节锂离子/锂聚合物电池的电量计（又称电量监测计、电池监视器或电池电量监测计）。它属于我们Smart LiB电量计系列产品之一，采用名为HG-CVR2的独特算法，即使在电池温度变化、负载、老化和自放电等不稳定条件下也能准确测量电池的RSOC（相对电量状态）。插入电池后只需设置几个参数，即可轻松完成HG-CVR2算法的配置，开始进行电池测量，大大降低开发过程的复杂性。LC709204F还包括SOH报告和多种集成警报功能，更好地支持电池安全。

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.)
