    Hello, I have a circuit that will need to return connected hardware to a default state if power is lost. The hardware can handle continuous voltage, so I’m thinking a simple solution would be to use a battery to provide that fallback power source. To avoid draining the battery, I’d like to connect it through a relay on the normally open contact and energize the relay directly from the main power supply on my board.\n
    \n
    Do I need to look for anything in particular to make sure the coil on the relay I choose can sustain constant voltage for potentially months at a time without damage? Or, is there another similarly low cost and simple solution you’d recommend?\n
    \n
    The circuit runs on 12VDC from a [Mean Well IRM-10-12 ([specification](https://www.meanwellusa.com/webapp/product/search.aspx?prod=IRM-10)), and the relays I have on hand are OMRON G5LE-14-CF 12VDC ([specification](https://omronfs.omron.com/en_US/ecb/products/pdf/en-g5le.pdf)). I don’t see anything on the relay documentation that specifies a maximum duty cycle.

      Hello, I have a circuit that will need to return connected hardware to a default state if power is lost. The hardware can handle continuous voltage, so I’m thinking a simple solution would be to use a battery to provide that fallback power source. To avoid draining the battery, I’d like to connect it through a relay on the normally open contact and energize the relay directly from the main power supply on my board.\n
      \n
      Do I need to look for anything in particular to make sure the coil on the relay I choose can sustain constant voltage for potentially months at a time without damage? Or, is there another similarly low cost and simple solution you’d recommend?\n
      \n
      The circuit runs on 12VDC from a [Mean Well IRM-10-12 ([specification](https://www.meanwellusa.com/webapp/product/search.aspx?prod=IRM-10)), and the relays I have on hand are OMRON G5LE-14-CF 12VDC ([specification](https://omronfs.omron.com/en_US/ecb/products/pdf/en-g5le.pdf)). I don’t see anything on the relay documentation that specifies a maximum duty cycle.

    I’m curious and am playing around with a new EDA tool and am looking at practicing by designing a PCB which should be roughly 28x26mm footprint (give or take a few mm…).\n
    \n
    It should be an LTE cat 4 device, connected by USB type C for the framework laptop and is unlikely to include antennas.\n
    \n
    Where I struggle is identifying potential modems to use. The only one even remotely close is the u-blox LARA-L6, which is 24x26mm. What alternatives are there?\n
    \n
    I am trying to see what gets sold in these USB dongles but there is little info. The few I have identified seem to make use of the Qualcomm 9207, but its’s unclear to me if its a ready chip (which is what the MDM9207 is?) Or if it is an IP core to integrate in one’s own chip?\n
    \n
    A video I came across seem to indicate it (the MDM version) is tiny:\n
    \n
    [www.youtube.com/watch?v=ToCyUCIoXEM](https://www.youtube.com/watch?v=ToCyUCIoXEM) at 2:13\n
    \n
    But will probably needadditional things to be integrated and I created an account at Qualcomm but they won’t give anything unless I’m certified from a company to be a customer and actually integrate it…

    I’m curious and am playing around with a new EDA tool and am looking at practicing by designing a PCB which should be roughly 28x26mm footprint (give or take a few mm…).\n
    \n
    It should be an LTE cat 4 device, connected by USB type C for the framework laptop and is unlikely to include antennas.\n
    \n
    Where I struggle is identifying potential modems to use. The only one even remotely close is the u-blox LARA-L6, which is 24x26mm. What alternatives are there?\n
    \n
    I am trying to see what gets sold in these USB dongles but there is little info. The few I have identified seem to make use of the Qualcomm 9207, but its’s unclear to me if its a ready chip (which is what the MDM9207 is?) Or if it is an IP core to integrate in one’s own chip?\n

    A video I came across seem to indicate it (the MDM version) is tiny:\n

      I’m curious and am playing around with a new EDA tool and am looking at practicing by designing a PCB which should be roughly 28x26mm footprint (give or take a few mm…).\n

      It should be an LTE cat 4 device, connected by USB type C for the framework laptop and is unlikely to include antennas.\n

      Where I struggle is identifying potential modems to use. The only one even remotely close is the u-blox LARA-L6, which is 24x26mm. What alternatives are there?\n

      I am trying to see what gets sold in these USB dongles but there is little info. The few I have identified seem to make use of the Qualcomm 9207, but its’s unclear to me if its a ready chip (which is what the MDM9207 is?) Or if it is an IP core to integrate in one’s own chip?\n

  +body: """
    This photo shows the power conversion side of two versions of the same board. Input is up to 60V DC, board converts to 5V and then down to 3.3V.\n
    \n
    The top board works correctly all the time. But the bottom board has strange issues. Everything works perfectly when I connect it to my bench power supply at 53V. The board powers up with no problems. When I connect it to the daisy chain of other boards, it suddenly will no longer power on, despite ~54V being passed through correctly to downstream boards.\n
    \n
    This is a real head-scratcher for me, and I’m having trouble making sense of it. I’m not so much looking for The Solution as to what steps I should take to troubleshoot this. There were some issues attaching the image, so in case it doesn’t show up.\n

        What do you mean by extra traces by the IC? And you’re absolutely right about the small IC. It’s the MAX17640, and at 2mm x 2mm it’s a piece of work to land correctly.

    This photo shows the power conversion side of two versions of the same board. Input is up to 60V DC, board converts to 5V and then down to 3.3V.\n
    \n
    The top board works correctly all the time. But the bottom board has strange issues. Everything works perfectly when I connect it to my bench power supply at 53V. The board powers up with no problems. When I connect it to the daisy chain of other boards, it suddenly will no longer power on, despite ~54V being passed through correctly to downstream boards.\n

    This is a real head-scratcher for me, and I’m having trouble making sense of it. I’m not so much looking for The Solution as to what steps I should take to troubleshoot this. There were some issues attaching the image, so in case it doesn’t show up.\n

      This photo shows the power conversion side of two versions of the same board. Input is up to 60V DC, board converts to 5V and then down to 3.3V.\n

      The top board works correctly all the time. But the bottom board has strange issues. Everything works perfectly when I connect it to my bench power supply at 53V.

    Thank you, I will reflow C4 and add C16, but C10 and C14 look fine from the sides.\n

    The messy/missing joints near C17, C19, and C20 are optional components for the other side. (Unused surface mount USB port with through-hole mounting pins and an unused jumper.) Right-hand jumpers are all optional and unused from an earlier prototyping stage.\n
    \n
    What do you mean by extra traces by the IC? And you’re absolutely right about the small IC. It’s the MAX17640, and at 2mm x 2mm it’s a piece of work to land correctly.

          Correct, it’s a switching converter, the MAX17640. 5V is not powering up (getting ~2V out) and then the 3.3V LDO is not powering up.\n

          I put an older variant daisy-chained board before and after the newer board. Both of the older ones come up, but the newer one doesn’t.\n

      This photo shows the power conversion side of two versions of the same board. Input is up to 60V DC, board converts to 5V and then down to 3.3V.\n
      \n
      The top board works correctly all the time. But the bottom board has strange issues. Everything works perfectly when I connect it to my bench power supply at 53V. The board powers up with no problems. When I connect it to the daisy chain of other boards, it suddenly will no longer power on, despite ~54V being passed through correctly to downstream boards.\n
      \n
      This is a real head-scratcher for me, and I’m having trouble making sense of it. I’m not so much looking for The Solution as to what steps I should take to troubleshoot this. There were some issues attaching the image, so in case it doesn’t show up.\n

    Correct, it’s a switching converter, the MAX17640. 5V is not powering up (getting ~2V out) and then the 3.3V LDO is not powering up.\n
    \n

    \n
    I will check soldering disturbances and put my scope on the input line to see if there’s a lot of noise. Thank you!
