Need some advice regarding an observation with the BQ25190
We noticed that the I2C locks up easily, if there is a small interruption on the lines.
Most ICs can recover from this or can be…
Part Number: BQ25190 Tool/software: Thanks for reaching out. I have a few questions to help narrow this down:
Is there a consistent bus state when I2C is locked? Is SDA low while SCL is high? Is SCL stuck low?
[Reply]In some cases its only one…
Part Number: BQ25190 Tool/software: Hi, this is Gilhwan Cha.
I am trying to create a custom board using the BQ25190.
The pitch and pad size of the BQ25190 seems to be too small to route the internal signals of the package on the PCB. Also, drilling…
Part Number: BQ25190 Tool/software: Hi, this is Gilhwan Cha. I am trying to estimate the SOC of a Li-ion battery by measuring its voltage through the internal ADC of a BQ25190EVM.
I measured it through TIcharger_gui: Here are the results of my experiment…
Part Number: BQ25190 Tool/software: Hi,
I have confirmed that the BQ25190 is controlled via GUI, now I want to do I2C communication with MCU, where can I find the example code? The I2C protocol or details do not exist in the datasheet.
Thanks.
Part Number: BQ25190 Hello:
Please help recommend suitable TI chip for charging IC, There are several requirements as follows:
1. The charging IC needs to have its own SOC and support I2C communication with downstream devices (battery meters); 2.…

Part Number: BQ25190 Tool/software: I am designing a battery-powered device and trying to minimize the BQ25190 Iq. Does the ADC always has to be enabled when the battery is discharging to monitor the battery temperature? My understanding is that enabling…
I should note: I have read through the response in another thread https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1484104/bq25190-register-setting-initialization-issue-in-bq25190/5701768#5701768 and the part…
Part Number: BQ25190 Tool/software: Hi, this is Gilhwan Cha.
A buck-boost rail grounding and short-circuit issue occurred.
It was in use on a custom board, and the decap configuration utilised the same decap as the EVK.
The problem arose when the…
