TPS22971: Automotive qualified version of TPS22971

Ryuji,

The TPS22918-Q1 device is available, but it only supports up to 2A.  Is this a processor rail that requires switching?  What is the continuous vs peak load current requirement?

Hi Ivan san,

Yes, we would like to use the device for turn off sequence of the processor.
The requirement is 1V/4.4A.
Thus , we would like to use TPS22971 as parallel using.
I will check the TPS22918-Q1 specification but if there is any plan to release of TPS22871-Q1 , please let me know.

Best Regards,
Ryuji

Hi Ryuji,

Have you taken a look at the TPS22966-Q1? This is a dual channel device with each channel rated for 4A. By putting the two channels in parallel, the device would be able to handle the 4.4A load at 1V. Would this solution be acceptable for your application?

Thanks,

Hi Alek san,

Thank you for your reply.
Yes, houwever the TPS22966 require the Vbias and the Vbias range is 2.5V~5.5V.

Hi Ryuji,

Is there no other rail in your system you can use for the VBIAS rail?

Thanks,

Alek Kaknevicius

Hi Alek san,

There is the 3.3V rail but the 3.3V is powered down before 1V rail.
Thus, I would appreciate if there is other device which is operated as No Vbias.

Best Regards,
Ryuji
