BQ500414 wireless charger solution

zane

Hi all, I've created a wireless charger base on BQ500414 solution, all signal of BQ500414 input is OK(such as VCC,REST,EN_PWR etc.), but no PWM output from DPWM_A(pin12). Could you please tell the condition for PWM output? Thanks

Hello Zane
Take a look at the FAQ section the presentation "TX trouble shooting Guide ".

bq500414 does not have a low power mode and will be on all the time. You will see a digital ping every 5 sec and short analog ping every 500mS.

Hello Bill,
bq500414 is base on Qi 1.1 standard, as a stupid question, does this IC solution can pass Qi 1.2 certification?

Hello Zane

The bq500414 will meet Qi 1.2 requirements and can be certified under the new standard.

This is also true for all TI WPC 1.1 transmitters.

Hi Bill,
As I know, BQ500414 is designed for 12V system, however, it's applicable to other supply voltages. Could you please tell me the range of supply voltages. I want to use this chip for automatic symptom which voltage is from 9V to 16V.
