TPS25865-Q1: Current limit

Cedrick

Part Number: TPS25865-Q1

Hi,

Good day. I hope you are doing well.

Our customer have a technical implementation question.They are using TPS25865-Q1 and they want to know if they can set a different max current limit for the bus out. The connector that they use will get too hot at the max current so they need to limit Ideal max output current is 1.5A. I believe the chip is ~2.4A for each bus, so ~5A total. They need the single output to be 1.5A. Would that be possible?

Looking forward to your inputs. Thank you.

Regards,

Cedrick

Hi Cedrick,

No, it is impossible due to there is only one DCDC for two ports.

Hi Ansel,

Thank you for your response.

Our customer has a feedback on your answer: I am actually only using one port- and was hoping there was a way to limit the single switcher to 1.5A considering I am only using one port. I'm sorry I didn't say that at the beginning!

Can you please let us know if they can limit the output?
Thank you.

Regards,

Cedrick

Hi Cedrick,

No, it can not be changed for Type A device. If customer needs to adjust current limit, they can select TPS25850/8 for Type A application.
