TPS2552DBVEVM-364: Whether the chip can automatically recover after an overcurrent event occurs

Hi TIer

Is my customer right when they say they tested TPS2552EVM found that when overcurrent occurs, EVM needs to power it back up to get the chip back to work?
I read the datasheet we are auto-recovering and in hiccup mode, right? Is there anything I need to set up?
Also, my customer wants to use TPS2552D, is this chip the same as the TPS2552 in terms of recovery mode? My customer is looking forward to a hiccup pattern that automatically recovers

Thank you very much.

Hi Yuxi,

Is the customer reporting that the device enters thermal cycle (or hiccup mode) when there is an overcurrent condition, but when the overcurrent condition is removed, the device does not come out of thermal cycle unless it is POR?

Are they are not seeing what it shown in Figure 5 or Figure 7 in the datasheet?

BR,

Seong
