Wireless Qi Charging

by jxz92999 on Thu Jun 03, 2021 3:44 pm

HI,

I've purchased the 2162 Qi charging transmitter alongside the 1901 Qi charging receiver and I'm wondering if you can provide the schematics for both. If needed our company can sign an NDA or other legal documents needed to obtain this information

Regards

We don't make those, so we don't have any design documents for them.

I'm afraid our supplier contracts forbid sharing source information with third parties.

If you're looking for reference designs, a surprisingly large number of products are little more than the suggested application circuit in the datasheet for the main device. I know TI makes Qi drivers, and their application circuits tend to be solid designs.

I completely understand. Could you at least tell me what the inductance value is of the transmitter coil?

Not offhand. We haven't torn them down to characterize them. You'll need to do that yourself.
