Hello,
We are implementing the BQ25895 in a battery-powered consumer electronics device. The max battery charge current is 900mA. We need the charger to detect automatically the…
Howard,
VBUS_GD bit is always set the first, then VBUS_STAT & PG_STAT bits are updated.
It depends. VBUS_GD means a valid power source is present while PG_STAT means VBUS power is ready for the charger to operate.
It is highly recommended to get…
Part Number: BQ25895 Dear all:
I use 5V/3A adapter connected to bq25895EVM-664 test when the battery does't exist,the SYS Pin loaded with 2A without output.the register configuration is BQ25895 battery doesn't exist.zip
I want to know how to set up…
Hi Jeff.
I bought yesterday the BQ25895EVM-664, it will arrive on monday. I test the same conditions on monday or tuesday and put the results here. Before that I want to post you the layout of the board for if you can see any thing in the planes of the…
Hey Tao,
Do you have the characteristics of the 60W panel that would be connected (i.e. VOC, ISC, VMPP, VSC)?
As far as the reference design, do note that it was created for single-cell low/medium power solar applications (<10W). The devices used in…
Hi Joel
We are using an unmodified Eval board (BQ25895EVM-664). Circuit diagram attached. At the moment it is powered from a bench power supply giving 5.0V at the VBUS/GND (J1) terminals of the board. The load is attached to PMID/GND (J2) terminals and…
Other Parts Discussed in Thread: BQ25895EVM-664 , BQSTUDIO hi,
I am not able to get the BQ25895EVM-664 Eval Board to work as expected. Refer to the below snapshot of the BQStudio.
Input J1 : 5v/3A Power Supply
Input VBUS Voltage = 4.8v (This is as per spec…
Part Number: BQ25895 Other Parts Discussed in Thread: , BQSTUDIO Hi
I have a development board BQ25895EVM-664,and test it as 4.5A Charge for 8000mAh Li-lion battery,is work well, then I Design My board by BQ25895,has some issue,first my sch is this …
Hello Felix, You best path forward is to either purchasing the EVM through the TI Store here:
Or
Since you are are a student I would recommend looking into our university programs here:

The bq25895 datasheet is available here: .
The datasheet has a typical design at the end of the datasheet. The evaluation board can be ordered from here:
