Hello,The STUSB4710 is a standalone chipset designed for SOURCE role only. As specified in the standard, at connection the Data role must be aligned with the Power role, so STUSB4710 is the Host (DFP). Then, the STUSB4710 does not support the Data Ro...
The Rx coil inductance (26µH) seems high.As the ratio between Rx and Tx coil is high, it generates high voltage on Rx. If it triggers over-voltage protection, the Rx could short Vrect to GND (to confirm as it is not a ST chipset), generating high cur...
Hi Mike,I confirm that if you target 5V output at Rx side, you should supply the STWBC86 with 5V.What is your targeted current at Rx side ? And please describe your receiver.What is the inductance value and the size of your Tx coil ? Finally, please ...
Hi,The communication from Tx to Rx is not possible using the GUI.Indeed, the Qi standard specifies that the response to a Rx packet must be initiated after 10ms and no longer than 15 ms after the incoming message is received.You need to use a MCU wit...
Hi Filippo,As you want to send a proprietary message, you must add a PP header so that it is recognized by the Tx.For "AA" sending, you must write AA 18 in the register (0x18 is the header defined by the Qi standard to send 1 byte):If you want to sen...
