LTC4231 retry period time

Category: Datasheet/Specs
Product Number: LTC4231

Hello,

Could you support on the following topic?

I am using LTC4231HUD-2#PBF which has the retry feature each 500ms typ according to the datasheet

But during testing shortcircuit at the output I see about 100ms between retries as shown in the following screenshot:

Yellow colour signal is input voltage

Green colour signal is output voltage. It is close to 0V because output is shorted

Blue colour signal is output current

The following image shows a detail for one of the peaks from previous image.

Overcurrent detection seems to work well because I have Rsense 1.5mohms which means about 33.33A circuit breaker threshold and Ct 22nF which means about 500us circuit breaker delay

Why retry is 100ms (tested) instead of 500ms (specified in the datasheet)?

Thanks in advance, best regards.
