TPS2595: EN pin timing

Patrick Chen(TPE System & Application)

Part Number: TPS2595

Hi Sir,

My customer is using TPS2595 and use a MCU to control the EN pin.

They are asking if they drive EN pin high before voltage supply to IN, is that ok?

Is there any risk like IC damage or any fault might occur?

Many thanks,

Patrick

Hi Patrick,

I don't see any issue in driving the EN pin before voltage supply to IN. Let me check with the design team and confirm to you by tomorrow.

Hi Patrick,

There should be no issue when EN is applied voltage before IN.

Hi Praveen,

One more question, Are you able to help let us know what feature we implement to make sure there is no problem on the EN apply first condition?

Many thanks,

Patrick
