BQ20Z75-V180: The static current of BQ20Z75 is on the high side

Part Number:BQ20Z75-V180

Hi Sir

I have a customer who is using BQ20Z75 and finds that the static current is abnormal. About 8% of the chip's static current exceeds 600uA, but the specification does not indicate the exact range of the static current. How can I persuade the customer that the static current of 600uA is normal.

There is only a median in the specification
