Other Parts Discussed in Thread: BQ500511
Tool/software:
Hi TI team,
Due to China SRRC Regulation, we need to adjust the TX frequency band from 110Khz-205khz to 100KHz-148khz.
The feedback from TI suggests that they had already planned for this and there is a pin that can be conditioned on their chip set to force the Transmitter to the 100KHz – 148-KHz band.
A board change will be required to add a pull down resistor o pin 33 of TI chip bq500511.
We need to know what value this resistor should be changed to in order to meet the SRRC requirements for 100-148 KHz.
Currently, our resistor value is 10K, a
nd the measured operating frequency is 170 KHz.
