Part Number: BQ25125 Other Parts Discussed in Thread: BQ25190 Tool/software: Hello,
I’m using the BQ25125 in my design and running into an I²C communication issue. The MCU is operating at 1.8V logic, and I can communicate with the BQ25125 without problems…
Part Number: BQ25125 Tool/software: Hi all,
We're using BQ25125 in a wearable application.
In the register 0x00, we're having always 0xC5 meaning that there is fault. However in all registers we cannot find any status in error. Below are all registers…
Part Number: BQ25125 Tool/software: Hello TI Support Team,
I am experiencing an issue with the BQ25125 battery management IC on my custom board. Specifically, when the battery voltage (VBAT) drops below 3.2V, I²C communication with the BQ25125 becomes…
Part Number: BQ25125 Tool/software: Hi Team
as datasheet mention. our BQ25125 have VBAT MONITOR feature.
do we have limitation or accuracy unstable if the battery capacity is too small?
below is current target battery spec.
1Cell …
Part Number: BQ25125 Tool/software: Hello,
I'm reopening the discussion on an issue I encountered with the BQ25125 battery charger IC. In my previous thread, I noted that the system works fine with ICHRG set to lower values like 20mA, but setting it…
Part Number: BQ25125 Tool/software: Hello,
I have seen a failure where it seems that the BQ25125 discharged a battery below the threshold set in UVLO register.
I thought this part provides under-voltage protection - am I incorrect about this ? …
Part Number: BQ25125
Tool/software:
Due to space constraints I have to use a very small SMD inductor on the SW pin.
The datasheet recommends to use a 2.2µH inductor but these are not available in sizes smaller than 0603.
I found a small 1.5µH…
Part Number: BQ25125 Tool/software: Hi,
We would like to generate a reset pulse when we plug a charger.
Our idea was to connect /PG output to /MR input, so a reset pulse is generated when a valid power input is present. This work well but we observe…
Part Number: BQ25125 Tool/software: I experience that Register 0x00 = 0xC1 (Fault: yes and VINDPM: not active), but none of the status flag seems to be set. That is, Register 0x01 = 0x00 and 0x02 = 0x80. There is frequent I2C communication, so this shouldn…
Part Number: BQ25125
Tool/software:
The FAQ post says PGND and GND need to be tied together.
Also the BQ25125 Schematic Checklist mentions "Ensure USBGND and PGND are tied together." which I think is an error (there is no USBGND) and means GND.…
