您好，请参考下面文档，确认cell balance设置是否有问题。

如果还没有解决您的问题，请详细描述一下您的balance设置。

BalancingConfiguration寄存器设置为0x04，其余寄存器都未设置，使用的默认值

您好, The BQ76952 will measure current through sense resistor and this current can be monitored at CC1 current. The BQ76952 will enter sleep/ relax modes when CC1 current is less than Chg/DSG Current thresholds. at this point the current should be very close to 0A.

Note: By default, the sleep current is set to 20mA. Please check your sleep current and make sure this is not too big.

Please check in your settings if Settings:Configuration:Power Config[SLEEP] is set. This bit allows the device to enter sleep mode. More on this in section 7.3 SLEEP Mode in TRM

In my test, sleep mode is forbidden. And I use host control, so it should not be affected by sleep mode.

您好，您设置的BalancingConfiguration寄存器设置为0x04，建议设置CB_NOSLEEP为0，CB_SLEEP为1再试一下。
