TPS2553D: Over current detection

Part Number: TPS2553D

Hello team,

The TPS2553D does not have two current limit values like the following pictures, is it right?

The TPS2553D can detect the over current when the current exceeds Ios more than 2us typ, is it right?

Hi Takahiro,

Welcome to E2E! Since it's a long weekend here in the US (Labor Day Holiday), one of our engineers should get back to you by Tuesday :-)

Hi Takahiro-san,

Yes, TPS2553D only have one current limit set by resistor.
Regarding to response time, it's related with output current. It's short to ground, the response is 2us.
For other loading, pls refer to datasheet page 10, current limit response time.

Best regards,
