Part Number: BQ25619
Hello,
We are using I2C controlled 1.5-A single cell buck battery charger BQ25619 and the the radiated emissions are over 47dBuV/m.
When testing with BQ25619EVM can see similar results, could you please advise if there is anything…
Hello,
Thank you for reaching out via E2E and sharing your measurements register settings. I have a couple questions based on your initial post.
-Are these observations being made on our BQ25619EVM or with your own PCB?
-You mention you shorted PMID?…

I tested by bq25616EVM about OTG mode. but something is I can't understood.
I need two action in 1USB port. If charger connected then action…
Hi switch,
I2C communication is possible as soon as VBUS rises above VBUS_UVLO or VBAT rises above VBAT_UVLO threshold (See below picture from datasheet):
However, I2C communication can only function if you have the SDA and SCL lines pulled up above…

Part Number: BQ25619 Hi Team,
I am using BQ25619EVM and checking the SYS pin performance. I notice when battery is removed(keep JP7 inserted, so 10K NTC still on board), the SYS ripple will be large - about 200mV peak to peak, and LED_D5 blink quickly…
Part Number: BQ25619EVM Other Parts Discussed in Thread: BQ25619 , BQ25601 Hi TI team,
I buy a BQ25619-EVM from ti-store.
After USB plug-in, I found the SYS voltage is 4.2V without battery connection.
Due to without battery connection(VBAT=0<VSYS_MIN),…
Part Number: BQ25619EVM Other Parts Discussed in Thread: BQ25619 Hi TI team,
I have a doubt about the difference between CHG_CONFIG and BATFET_DIS.
If set CHG_CONFIG=0, it will stop battery charge immediately by turn off BATFET.
If set BATFET_DIS=1, it…
