I have selected NXQ1TXH5 wireless power transmitter in my new design. Please provide the programming method for this NXQ1TXH5 chip.

1. Please suggest the wireless power receiver part number.

2. Can i use the BQ51050B wireless power receiver part to communicate with NXQ1TXH5 wireless power transmitter.

Please provide your feedback.

Hi,

The NXQ1TXH5 is an easy to use, fully integrated chip, that can be completely configured by means of external resistors, so there is no need for customers to have access to the I2C bus to configure/program the chip.

MWPR1516 wireless charger receiver will work with any Qi transmitter including the NXQ1TXH5.

I’m unfamiliar with the BQ51050B, you need to check directly with TI about this compatibility, however, since it is a Qi certified wireless power receiver, it should work fine.

Regards,

Jose

Please provide the MWPR1516 EVK references and minimum RX coil size can we use for 1 W application.

Here you can find the 15 W LDO Wireless Charging Receiver Reference Design: https://www.nxp.com/design/designs/15-w-ldo-wireless-charging-receiver-reference-design:RDWPR1500-LDO

And here you can find the 15 W Buck Wireless Charging Receiver Reference Design: https://www.nxp.com/design/designs/15-w-buck-wireless-charging-receiver-reference-design:WPR1500-BUCK

Unfortunately there is no recommendations for the RX coil size
