TPS2553: the fault condition to trigger device turn off

Part Number: TPS2553

Hi team,

My customer use TPS2553 in their application. Now they have a question on our TPS2553, when will it be turn off and retry to turn on?

As shown in datasheet, Figure 4. Full-Load to Short-Circuit Transient Response and Figure 6. No-Load to Short-Circuit Transient Response, there is a turn off due to short-circuit, while in Figure 8. No Load to 1-Ω Transient Response, the device just enter into current limit mode without turn off. So the question is what condition will trigger the turn off and retry? Is the output current level or the current ramp up slew rate? Thanks for your help.

BRs,

Binbin Wang
