Part Number: BQ25886 Hello E2E forums,
For the Bq25886 EVM CE/OTG D+ and D- pins. If we wanted the charger to accept that maximum input current once a 5V supply is powered in would we have to do the following:
Have the CE and OTG pins pulled low. …
Part Number: BQ25886 Hi team,
I got a question from customer.
When using bq25886 to charge two lithium batteries, we encountered the following problems:
The 1A charging current (external adapter) is only 290ma, and it is useless to adjust the ground resistance…
Part Number: BQ25886 Please let me know about the electrical specification for internal FET, QHS and QLS by datasheet P13.
I especially want to know parasitic capacitance, rise time, and fall time (and the other delay time).
Part Number: BQ25886 Hello,
On page four of the datasheet it says the battery charge voltage limit can be either 8.2, 8.4, 8.7 or 8.8. I am confused why TI chose 8.7 and 8.8 because no battery chemistry charges to 4.4volts and only lithium rechargeable…
In order to allow up to 3A of input current from the adapter, you can short the BQ25886's D+ and D- pins together so that the BQ25886 detects a DCP and sets the input current limit to 3A. You don't need to connect the BQ25886's D+ and D- pins…
Part Number: BQ25886 Other Parts Discussed in Thread: BQ25730 , BQ25792 Hi Team,
I want to find a chip that can support power delivery and sink function. I think BQ25886 is suitable. What others can support these requirements?
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 Hello
Please we have a problem in the production version of our product.
We used the same schematic in the board we designed for internal tests, it worked correctly, but when we redesigned the PCB, the IC stopped to work.
