bq20z451均衡保护

请教各位大神一个问题，我做的是3串的电池，该电池在放电末端时，cell 之间的压差接近300mV，那么IC满足什么条件才触发保护(cell 之间的压差大于多少)？

请参考下面的描述：

Cell Imbalance Fault— Two methods of cell imbalance detection are implemented to provide CIM
detection both while charging and at rest. Two safety CIM flags are used, one for each detection
methods. CIM_A reflects faults detected using the active CIM detection and CIM_R reflects faults
detected using the at rest CIM detection.
At Rest Detection
The at rest detection mechanism starts detection if all of following conditions are reached:
• Any (CellVoltage4..1) > Rest CIM Check Voltage
• |Current| ≤ Rest CIM Current for CIM Battery Rest Time
The bq20z40-R1/bq20z45-R1 sets [CIM_R] in PFStatus and goes into permanent fail condition if
the following condition is met and remains active for more than Rest CIM Time period:
• Max difference between any (CellVoltage4..1) > Rest CIM Fail Voltage
Set Rest CIM Time to 0 to disable this CIM detection.
Active Detection
The active detection method during charging is activated when the following conditions are met:
• Any (CellVoltage4..1) > Active CIM Check Voltage
• Current ≥ Charge Detection Current
The bq20z40-R1/bq20z45-R1 sets [CIM_A] in PFStatus2 if the following condition is met and
remains active for more than Active CIM Time period:
• Max difference between any (CellVoltage4..1) > Active CIM Fail Voltage
Set Active CIM Time to 0 to disable this CIM detection.
