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!

Currently the TI page tells me that Arrow should have some in stock (just click on the 'Buy from distributor' link, then it tells you which one has stock). Unfortunately they too have a minimum quantity of 250: BQ500212ARGZT - Texas Instruments, Power Supply Controllers and Monitors. Order from Arrow Electronics. Maybe you can ask them what lower quantities would cost?
Did you try to order the samples with TI? They should tell you somewhere in the process when they would be shipped...

I did order the samples, but the only information I got was that they were on backorder. I have contacted both TI and Arrow and asked for single quantity prices or expected delivery dates, respectively. Let's see.

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.

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...
