Hello
TIDA-00451 is a half bridge coil drive, it will have lower gain. BQ500212AEVM-550 is a full bridge coil dive and will have higher voltage gain.
Advantage of the 00451 is a lower parts count and lower cost.
But the bq50002A / 511A system is released…
Hello
The bq50002A / bq500511A will support Qi standard (WPC). If the RX is certificated to the standard and displays the logo it should work.
I have no specific information on the Apple Watch.

I have following setup: the charger is made up of the bq500511A/bq50002A combination and the receiver is a bq51003 followed by a bq25100 for charging a Li…
Part Number: BQ51003 Other Parts Discussed in Thread: BQ50002A , Hello.
I found a equation on bq510003 datasheet on page 27. if use fs=10KHz, fd=1MHz, and Ls value is fixed. therefore C1, C2 will be worked out.
But I use EVM parameter Ls=10uH to work out…
The bq50002A is the power supply for bq500511, 3.0V LDO that is limited to about 14mA. The additional current to drive LED will come from this supply.
If you increase LED current slightly that will problem not be a problem.
Part Number: BQ500511 Other Parts Discussed in Thread: BQ50002A
In the datasheet of bq500511 and also bq50002a, there are some descriptions about the detecting RX in the PAD and steps to start-up charging, and the EPT, ending charge, etc.
Though I get…
Hi Trevor
Double check if you are using bq50002 / 511 or bq50002A / 511A. Devices cannot be mixed and the non-A should not be available.
What is the FOD loss running on the unit?

hello,
Could you please explain more details about FOD_CAL, and ralationship between FOD_CAL and FOD_THR
The test you are showing is a metal object on the TX with no RX present and power transfer not started. In this test the TX will remain in standby and only send a low power ping to check for RX, no power transfer will start. LED D1 only indicated power…
