概览

FFG3105 电池 ID 和智能充电监控器芯片适用于手机和其他移动设备中使用的电池组。FFG3105 具有两个可编程的 64 位寄存器，可用于存储电池的识别码。FFG3105 监控电池电压和温度，以提供有关这些值的精确信息。该信息可用于充电应用中，以确保最佳性能和安全性。FFG3105 包括集成的温度传感器和电池电压监控器。FFG3105 还包括 12 个 16 位寄存器，可用于存储电池参数和最新历史记录。安森美半导体的 FFG1040 这类系统侧电量计可以使用这些寄存器来加快在电池取出和重新插入后进行快速初始化或进行电池更换。主机可以通过 I2C 在标准模式或快速模式下访问包括温度和电压读数在内的所有寄存器。每个电池 ID 寄存器都有一个内部冗余副本，以提高稳定性并防止潜在的错过编程。FFG3105 采用 2 x 3 焊球、0.5 mm 间距、WLCSP 封装，标称尺寸为 0.96 x 1.66 mm2。

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.)
