Hi Team,
I am trying to understand the fault response of LM27402 to an overcurrent condition. Please refer to Figure 25 in the datasheet.
It says that the internal counter starts its 32 cycle count after the third overcurrent condition. However, the text immediately under the figure explains that it enters hiccup mode even though the 4th overcurrent and 5th overcurrent event occurs after 24 cycles. This is consistent with the text preceding the figure that says that the counter begins from the first event and that the device enters hiccup mode as soon as it detects 5 events in 32 cycles.
The figure is leading me to believe that it takes 3 overcurrent events to start the counter. I think it might need modification.
Thanks!
