Hi Satoshi,

There are no power off requirements for this device. VIN and VBIAS can be disconnected in any order and it will not damage the device.

Thanks,

Sorry for addition, is power up sequence also no problem?

I think that it is no problem because I found these answer for other load switch forum.
But customer hope to find the answer of "TPS22954 is no problem".
Please let me confirm TPS22954's power up sequence.

Hi Satoshi,

There is no required power up sequence for the VIN and VBIAS pins of the TPS22954. One can come up before the other or both can come up at the same time with no damage to the device.

Thanks,
