MMWAVEICBOOST: short curcuit on board

Sebastian Scholl

Part Number: MMWAVEICBOOST

Hello TI support,

we bought a new MMWAVEICBOOST device, but we are not able to use it, as the device has a short curcuit on the power input.

Kind regards

Hi Ishita,

be bought the device at the German Mouser Store about four weeks ago.

Since then we are discussing with Mouser what to do. To get an RMA, the Mouser technician wants us to ask here in the forum if this is a known/common issue.

Personally, I find it a strange question from them, nevertheless we need a working unit and thus some sort of replacement.

Regards,

Sebastian

Hello Sebastian,

Did you try to initially power the board on when you received it? If so, can you please provide the specs of the power supply you used?

Each board is tested after assembly so it should not have been sent to you with a short.

Hi Ishita,

we tried it with a 12-W USB power supply from Apple, this is specified with 5V, 2.4 A max.

In 2.6 Power Connections of the "User's Guide 60GHz mmWave Sensor EVMs", different configurations for board power are mentioned, one for 5V and one for higher voltages. I tested both configs, the short occurs with any of them.

Regards,

Sebastian
