Part Number: BQ25190 Hello,
We are currently developing a product that uses the BQ25190 as the main power management IC / battery charger. Our device incorporates a Li-Po pouch cell battery that is rated at 3.8V nominal and 4.3V charging. We have configured…
Part Number: BQ25190 Other Parts Discussed in Thread: BQ27427 , BQ27220 , BQ27426 Hello,
We would like to charge a battery and power our circuit using the BQ25190. We also want to incorporate a component capable of acting as a fuel gauge into our system…
Part Number: BQ25190 Hello,
We are using the BQ25190 for power management in a new portable device we are developing. We are utilizing both the Buck and BuckBoost converters to power different blocks. In the datasheet, section 8.2.2.2 discusses output…
Part Number: BQ25190 While developing a software driver for the BQ25190, I have noticed a substantial deviation between the documented ADC conversion times and what I am observing in practice. I am operating the ADC in single shot mode with all comparators…

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 Hi, please have a look at the attached schematics. The issue is that the FIXED IND 2.2UH gets heated as we connect the 5V IN in the board. This is specially true when the portion marked as 2 (companion board with AS7058 part) is connected…
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…
