ARULKUMAR YOVAN

Part Number: BQ51003

We have two types of wireless power receiver circuit. One circuit is made using BQ51050BYFPR(Texas Instruments) and another one is made using of BQ51003YFPR (Texas Instruments) , BQ25100YFPR (Texas Instruments) . And also we are using the two types of coil. The coil manufacturer part numbers are AWCCA-18R18H10-C01-B(Abracon LLC) , 760308201(Würth Elektronik)

The wireless power transmitter is VUSOLOBL-T (TYLT - www.amazon.in/.../ref=sr_1_25. Input of transmitter is DC 5V, 1.8A and the output is 5W.

We are tested the transmitter along with mobile phone, that is charging. But we are connecting our receiver circuit, that is not charging.

I have attached the schematic, testing setup images.

So please let me know, why our receiver circuit is not charging.

Advance in thanks.

Hello

Check the RECT pin on the BQ510XX, this will give an indication of what phase of start up or operating has problems.

See attached.6153.bqTESLA FAQ--Start up.pdf
