TPS2662: Keep drooped voltage state during current limit operation

Michiaki Tanii

Part Number: TPS2662

Hi team,

Are there any way to keep output voltage droops during current limit operation ?

In my understanding, TPS2662x should be turned off if the thermal shutdown threshold is hit or tcl(dly) is elapsed as described in the datasheet but if there are any way to avoid the shutdown, please let me know.

Thank you and best regards,

Michiaki

Hi Michiaki,

That's the way the eFuses are designed to protect the internal FET from thermal runway. Can you please let me know how much time you need to serve the load with Vout droop during current limit operation ? and why this specific function is required. ?

What is the end -equipment and use case ?

Best Regards, Rakesh
