Part Number: BQ51003

Dear Sir,

We are using BQ 51003 wireless charging IC , This IC has output power is 2.5 W and minimum charging input power is 5W. but in our case, we would like to use 2.5 W charging pad. So please suggest any idea for this and is there any equivalent IC?

Hello

A 2.5W Transmitter (TX) is not available, this also has some risk. Due to a couple of factors that cause loss and low efficiency the TX will send out more power to produce 2.5W at the RX output.

Thank you so much dear Bill

Does this IC support Apple I watch charging pad? Because our device is a smart band gadget so its size is low. We would like to charge our device with a less wattage charging pad.

Sorry but TI does not have a transmitter that will meet this requirement. All transmitters are NRND.

Hello

The BQ51003 Receiver is based on the Qi standard and will work with Qi transmitter.

We do not have an Apple specific device but if it is compatible with the Qi standard it will work.
