Part Number: INA219 Dear TI engineer:
Please find attached two snapshots of the waveform. These waveforms represent the execution of the same I2C code aimed at reading the INA219 power register.
However, the outcomes depicted reveal variations. The SCL…
Part Number: INA219 Other Parts Discussed in Thread: SYSCONFIG , INA226 Tool/software: Hi Team ,
We want to interface between ina219 sensor to ATSAMC21J18A (our microcontroller.
Kindly suggest reference code for that
Thanks,
Smruti
Hello Shiang,
Rev G is the latest datasheet, so you should use the timing requirements from that datasheet. Please let me know if you have any further questions.

Part Number: INA219 Hi team,
Customer feadback on their design, found some accuracy problem, please see below description, and some input to us on this modification, thank you.
In customer INA219’s R_shunt 0.25m ohm application, we use 0.25m ohm for…
Part Number: INA219 I attached the four consecutive test results here. Please let me know if you have any questions.
Waiting up to 45 seconds for Controller to POST.Time for POST=0000:00:00.000 Waiting up to 45 seconds for kernel to initialize... List…
Hi,
CP Poh1 said: in what circumstances that the failure can be narrowed down to system level issue instead of component level issue?
I attempted to replicate the issue on a different system, and we could not replicate it. This is what makes me believe…
Part Number: INA219 I have a 4S battery pack of Li-Ion batteries. Can I use one INA219 for each battery (e.g. four INA219 chips) to measure the current (charge and discharge) and voltage for each battery, and have that data accessible over the I2C bus…
Part Number: INA219 Hi,Team
We would like to design current sense circuit with INA219.
In circuit, input is 12V, max current is 10A
Which part do you recommend for current sense resistor?
thanks

Part Number: INA219 Hi,
I recently try to implement some firmware to read different ina219 on my PCB and I stumble with some issues with the reading of the current value. For some reason I can't find, I am not able to read a correct current value. I don…
Hi Comi,
The reason why the current and power register readings are incorrect is because the calibration register was programmed with the wrong value.
When programming Cal register, please don’t shift bits. 51EB (or 51EA) should be written to it directly…
