Dear teams,
我们客户用BQ76952有以下问题，麻烦您帮忙解答给点建议，谢谢！
当BQ76952处于sleep模式，并且开启充放电MOS管时，此时负载突然加电流，例如从0A到20A，AFE要等1秒才会读到20A的电流给到MCU, 这是AFE从sleep模式醒来的固有特性吗？
谢谢！

Star Xu：
您好，1S是固有特性，请参考TRM的详细描述：
When exiting based on current flow, the device will quickly enable the FETs (if the CHG FET was off, or the DSG FET was in source follower mode), but the standard measurement loop is not restarted until the next1-s boundary occurs within the device timing. Therefore, new data may not be available for up to ≈1-s after the device exits SLEEP mode.
