IWR1443BOOST: it previously work fine and then not switch on and not detected by computer too

Hello

This is usually not expected, would you be able to check/measure the output voltage on the PMIC ic of the device.

THank you,

Vaibhav

Hello

Sure i could do that, but could you tell me exactly where i have to place my voltmeter?

i have try to find PMIC output pins in  IWR1443 User's guide (document IWR1443BOOST Evaluation Module mmWave Sensing Solution User's Guide SWRU518D–May 2017–Revised May 2020 )

but i do not succed finding it to mesure its output voltage

thanks and have a nice day

Hi,

When did you get this board and how did it get damaged?

Hello

I buy mid 2018 but don t have too much time to learn to use it so i start  realy to use it since november.

and how it was damage? I don t know. i keep the card on a box and a day, it just don't start again, i always use the same power supply with it and the power supply still work fine

Regards,

Sebastien

Do you know if there is some waranty from TI? 

Because buying another card to have the same problem after few hours of work not sound's good?

Regards,

Sebastien

Thanks. unfortunatly, i have other priorities in 2019 and 2020 so i don t use it really and it s frustrating. i wish new card will last longer

i will try to find PMIC datasheet to check what outside but even it it s PMIC which fail, i am not equip to change that king of chip

thanks and have a nice day

Sébastien

Hello

Is there somebody who know how to test PMIC?  on which pin can i do measure that?

thanks and have a nice day

Sébastien

Great. it try that tomorow and let you know if that s the PMIC which is dead or not

thanks and have a nice day

Hello

is there anything to do to save the card?

thanks to all anyways for your help
