BQ51222: Need the LPRB Excel tool

Hi Vivek

The BQ51222 is a dual mode device supporting both WPC (Qi) and PMA standard, do not recommend this device.  A better device to look at is the BQ51020 / 021 they are WPC only devices they are P2P with 222.

 LPRB is for the PMA standard.

Hi,

Already developed the Gerber and the device is under prototype production. Will see the change in next production cycle. Meanwhile if the support can be provided, would be great. we have already managed the parts from TI and supplied to the manufacturer.

Moreover BQ51222 is cheaper, is v1.2 compliant and AVAILABLE (in stock) unlike the bq5102x.

We shall be using the bq51222 only with WPC

Hi

Unit will work well in WPC only mode.  The BQ51221 EVM can be used as a design guide for the BQ51222 applications.  The changes between BQ51221 and 222 are minor.

Recommend using RX coil with a higher L value for WPC only, see Wurth 760308103215 or  

Also the BQ51020 / 21 are v1.2 compliant

Will Vishay IWAS3010AZEB130KF1 do the job?

The coil, IWAS3010AZEB130KF1 --  is 10mm X 30mm that is on the small side this is bad and L is 12.9uH that is good.  

How much output current do you need?

Hi, let us try both and see.

Meanwhile we are using BQ25180 too. Any library available for this for nordic nrf5340?
