Part Number: BQ25886EVM Other Parts Discussed in Thread: BQ25886 When bq25886EVM with no battery connection (Vbus: 5V), 0.4A load became discontinuous switching and 0.5A load became Vsys: 0V.
Please let me know about three points below;
①Measure to stable…
Thank you. We do not have a BQ25886EVM but we have a BQ25887 EVM.
On another note: How do you program the charger using the D+ and D- pins. I see the tables near 8.3.3.3 on the data sheet. How would you program in divider 1-->2.1 amp input current?…
Part Number: BQ25886 Hi TI expert,
We designed the circuit by referring to the BQ25886EVM. I want to limit the input current 3A by applying the Input Current Optimizer (ICO). (short D+ to D-)
The charging current is set to 1.5A.
Could you review schematic…
Part Number: BQ25886 About efficiency data on datasheet Page 11, is there detailed test condition?
And, is test schematic nearly bq25886EVM (or datasheet page 25), correct?
【Background】
・Customer is measure efficiency on bq25886EVM default setting and…
Part Number: BQ25886 Other Parts Discussed in Thread: BQ25882 , BQ25883 , When no battery connection, is there control function for clamp the duty cycle?
I evaluating based on default bq25886EVM, but duty cycle become nearly 50% (worst case) and occur below…
Part Number: BQ25886 I have a BQ25886EVM evaluation board and my own board with a BQ25886EVM that I am comparing to each other. The Evaluation boards works as expected but my board is not.
In my troubleshooting I have noticed that on my board I am not…
Hi,
I had a problem with the OTG boot. I connect the BQ25886EVM to my system motherboard and battery, and the VBUS port is connected to the TYPE-C interface.
Now, when the system boots, an OTG line and a U disk are connected to the TYPE-C interface. When…

What is the principle of cell balance implemented in BQ2588x QFN EVM? Thank you.
Yashwitha,
The TS feature can be disabled by putting a fixed 10kohm resistor in place of the thermistor. This is not explicitly stated in the datasheet, but is mentioned in the BQ25886EVM user guide. These documents are also a good resource for your customer…
