BQ76952: During high current discharge of BQ76952, disconnect the discharge MOS Alarm Status and FULLSCAN will no longer be set to 1 unless BQ76952 is reset

Hi

I have a query need your help.

In the battery system of BQ76952, there are 16 batteries, and the voltage is about 52V. Now the current of this battery is 30A. The battery is connected to the inverter and the inverter has a load of 1500W; the circuit breaker cuts off the current. MOS, at this time, the microcontroller reads the BQ76952 AlarmStatus 0x62 status register from time to time, and the FULLSCAN is no longer set to 1 in the returned result; if the AlarmStatus status is not read regularly during the previous operations, FULLSCAN is set to 1; the FULLSCAN status is set to 1 for our program It is very important that the program displays information such as battery voltage and current based on this status;

When this problem occurs, we print out the register values ​​of BQ76952, register values ​​are normal.

Under what condition will FULLSCAN be set to 0?

Waiting for your reply.

Thanks
