AWR1843BOOST: Power supply

Wembanyama

Part Number: AWR1843BOOST

Tool/software:

hi, engineers

I'm so sorry to bother you, I accidentally inserted the lithium battery pack (12V) directly into the AWR1843boost board for about 3-4 seconds, I want to know if the board is burned out?

Does TI provide hardware protection? My AWR1843boost board can not work, at present, the first guess should be the hardware problem, how to repair from the hardware?

Regards,

Wembanyama

This is likely a board burnout. 1843Boost board is designed for 5V input.

Thanks,

hello,

how to fix the board,please?

whether there is protection circuit on the 1843boost board? so that I can replace some device？

And in order to figure out all broken devices with wrong power supply, could you give me more about 1843boost power circuit details in the PCB?

Regards,

Please check if the 5V and NRST LEDs power on when you connect a 5V input.

The buck converter converts the 5V to 3.3V. please probe the output of this buck converter to make sure you are getting the 3.3V

Hope this helps,

Hello,

You will find the EVM schematics and layout on the EVM web page. Please let us know if you are having difficulty locating it.

Also, please make sure the VBGAP is coming up and the XTAL is sending proper clock.

Thanks,
