Waterproofing marine equipment -12- Sourcing an IC

2 Jun 2014

Ok, I will confess: I'm probably the worst supply manager in the world. Not only did I get the wrong values and footprint for my resistors and capacitors on the receiver board, but I also noticed while assembling the transmitter that I had forgotten to order the most important part: the bq500212A Transmitter IC. After noticing I quickly went to the TI.com webpage to order a few samples. But, to my disgrace, it's out of stock and on backorder. Not a big deal I thought. I will have to buy a few. But neither Mouser nor Farnell sell these IC. And, here comes the problem, Digikey only sells them in 250+ quantity.

 

So I'm turning to any of you who might know where or how  I could source at least one chip to test my board. Any ideas? If I'm not able to source one I will think about redesigning the transmitter board to work with another available transmitter IC, but taking board manufacturing into account I would certainly have problems getting it finished for the 27th of June.

 

Thank you!

    Yes, it's always a strange feeling when you order a PCB... hope everything turns out ok!

    I hope you get it in time, it would be bad to miss the deadline because of that. For me its the PCB that will be a little bit late - I hope I didn't do any mistakes...

    Update: I got a response from TI, stating that the ICs are expected to be back in stock in 1.5 weeks. I also got a quote from the Jotrin, the Alibaba vendor suggested by Malcom. It's 9$ per chip, with 25$ express shipping.

     

    I think I'm going to wait for the TI samples and may finish the assembly just in time.

    Sadly this is not my case. It only says: "Items on backorder will be shipped as soon as they become available". The other samples I ordered already arrived at home, as fast as usual...

    In my experience they confirmation says when they expect the samples to arrive. But maybe this happens only when some parts of the sample order ship.
