BQ51003: BQ51003

Hello

The BQ51003 IC temperature will depend on the charge current, difficult to identify one temperature. Also the PCB and case design will change temperature.

Can you tell me more about Qi9WPC?

now we are investigating on this temperature issue, it means the max temperature of Tx side goes up to 58 degree while it's on charging. I'd like to know the max temperature to make sure the device is safe in Tx and Rx side. It could be fine for Qi spec as well as Chip spec. 

Hello

A thermal rise to 58 degrees is a little high, most devices want to keep the temp below 40C.

Have you built both the TX and RX?

Sure sir.  both Tx and Rx used Ti Chip for Qi wireless charging system, and we can see the hightest temperature goes up to 58 degrees while it's charging. I'd like to know the specification of the Qi systems.

Hi 

The Temp is high, and it is difficult to say what the cause is.  It may cause problems for FOD test if you plan to certify the unit.
