Part Number: TPS2363

Tool/software:

Hi team,

My customer would like to design PCIE Hot Swap function and they found TI has TPS2363.

But they saw this chip is old, we released on 2010.

So they would like to know does TI have new one?

Please advise.

Thanks

Hi team,

May I know can TPS2363 can use PNA/B pin to turn on or turn off power source?

Customer preferred they can independently control PCIE's external power FET.

Thanks

No, separate eFuse solutions can be used for each rail.

Yes can be used.

It can used independently.

Avishek,

Due to customer's output loading is large, so they are asking can they tie

1. Pin.out12A and Pin.out12B together for 12V output?

2. Pin.out33A and Pin.out33B together for 3.3V output?

Thanks

It's not recommended to connect the outputs because setting up the overcurrent protection thresholds is not possible. Instead, use a larger number of MOSFETs in parallel to support more load current.
