My customer initially has a wireless charger solution based on bq500211A, and is working fine.
They are working on a new design based on bq500410A. They have changed the supply voltage to 12V and the coil to A6 coil. Everything is working, except on CS100. When a fully charged RX device (a mobile phone) is place on bq500211A,, the bq500211A will indicate full charge condition within one minute.
However, when the same mobile phone is placed on a bq500410A, it takes 30-40 minutes to report that it is fully charged.
Is there any difference in CS100 implementation between bq500211A and bq500410A ?
Any other things have to be considered when changing design from bq500211A and bq500410A ?
