Part Number: BQ25892 What is TI's recommendation for P/N BQ25892 snubber design? Also, what other EMI reducing techniques are there for this device beyond the Layout Guidelines in the data sheet?
Part Number: BQ25892 Hi team,
Customer used BQ25892 before, but they now need a lower switching frequency charger with similar features and functions. I was wondering if you have any recommendation.
Thanks!

Part Number: BQ25892 Other Parts Discussed in Thread: BQ25890 Hey Team,
I might be mis-understanding how OTG works. BQ25892 has no D+/D- pins, how could OTG work without? I thought D+/D- were needed to negotiate host and know how much current and which…
Part Number: BQ25892 Hi team,
They customer is using the bq25892 and they set the charging current at 5A. They find that the charging current is 5A when the Vsys without load. But the charging current decreases to 4A when Vsys power supply the load(about…
Part Number: BQ25892 Hi team,
It is clear that BQ25892 can support 5A(the customer set the charging current)total between both battery and VSYS. So the charging current would be less than 5A while the VSYS are having load. The customer want to know whether…
Part Number: BQ25892 Hi expert,
Could you please advise what might goes wrong with the charging current at the red circle area that higher than REG04 Ichg setting 2048mA? It goes up to 2286mA and even over the Ichg accuracy 5%.
Regards,
Allan

Hi
The design is 3 series cells, the input power is 15V/6.4A. The charging current of the three series of battery packs can reach 8A. The NVDC battery pack is also required. Also need…
Part Number: BQ25892 Hi, im designing a charging circuit with the BQ25892. However, when the battery voltage drops below 3.5 V, VSYS is not regulated above 3.5 V. VSYS has unfortunately the exact same voltage level as the battery.
I measured the following…
Part Number: BQ25892 Hi expert,
May I check with you is there a threshold voltage in register would limit the write access and change the register value back to default if in battery mode only AND the Vbat lower than the threshold, maybe Vsys(min)? Customer…
