Part Number: BQ25895M
It is clear that the conditions for the end of charging are that the voltage meets the set 4.17v and the charging current is less than 64mA. However, the charging time of the BQ25895M charging IC is close to 12 hours, of which there…
Part Number: BQ25895M Other Parts Discussed in Thread: BQ25895 The device fails to charge a flat `liPo battery (flat , 0V as the isolation circuit in battery has isolated the battery as volage is below 3V).
The datasheet says it puts 100mA into a shorted…
Part Number: BQ25895M Other Parts Discussed in Thread: BQ25895 One of the features of the BQ25895M over the BQ25895 is PFM mode for the boost converter, to improve low-load efficiency.
However, I don't see any reflection of this in the BQ25895M data sheet;…
Part Number: BQ25895M Hello,
I have a project where I need a USB-UART Bridge (CP2102N-A02-GQFN28) to program and communicate with the MCU over USB. In a second project I use a MCU (ESP32-S3) with integrated USB functionality. In both cases I want the BQ25895M…
Part Number: BQ25895M Hi,
I am using BQ25895M with a generic 5V Vbus input source and not a USB 5V input source.
How do I connect D+ D- and DSEL pins?
I am not using any USB handshake protocol as it is not a USB charger I am plugging into Vbus. It is…

Hi Delish,
A table like the one you suggested in your last reply would be helpful.
Can you also provide a scope capture that shows VBUS, IBUS (input current), VBAT, and IBAT (battery current)?
When you have your input adapter connected to VBUS and the battery…
Part Number: BQ25895M Hello,
I would like to have the register settings reviewed to ensure that the settings are optimized for our use case.
Portable wireless charger
Battery capacity: 2000 mAh
Currently we set the max input current at 1A
At higher…
Part Number: BQ25895M I would like to keep the Boost Mode Voltage at 1110 for PMID OTG.
However, I am seeing the following
In load test, as I increase the load current on PMID from 0.2A to 1.5A, the boost voltage sometimes resets to the default value…
Part Number: BQ25895M Other Parts Discussed in Thread: BQ25895 , BQ27220 Hi,
We are developing a eNote Paper Tablet and running Linux . We have used BQ25895M as battery charging circuit and enabled the driver which seems works fine. When the system is connected…
