That is literally what I asked for, the name of a supplier.
This is why I don't use engineering forums to search for answers. I'm better off finding the answers myself.
I should have known better. I hate to judge an entire forum based on one person, but I will.
Goodbye edaboard.com, you are...
Does anyone know where (supplier or company) I can purchase lithium ion cells without the protection IC already attached to the product? I already have under and over voltage protection on my board, and I'd like to directly solder the cell tabs in order to save cost during production.
Here is...
Also I wanted to point out that I must use resonant charging and not inductive, since my coil size must be tiny and the distance must be at least one coil width. Qi uses inductive charging which is not a technology I can use. Resonant frequencies are commonly at 6.78 MHz. I did do EM analysis in...
I have no feel for how much power what I made is transmitting into the air, and I don't know how to measure it. I don't know what frequency is best to use.
Greetings.
I've designed and manufactured about 20 units of a small wireless charger for a product I am working on as a side project from my day job. The charger is very simple: 5VDC from USB-C source, boost converter to 12VDC, and then a low power H-Bridge (UCC37321 / UCC37322 opposite each...
