Part Number: INA219 Tool/software: Hi team,
My customer use the INA219B in their below application, and the shunt resistance is 0.05 ohm, the current is 1mA, so if the device can recognize such a small input?

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…
Part Number: INA219 Hello,
We are usign INA219 for a Shunt voltage measurement through a 4.99 Ohms Sense resistor and approximate current ~18mA. The Bus voltage is 12V. When we measure the drop across the sensor resistor, we are able to see 90mV, but…
Part Number: INA219 Tool/software: Dear engineer,
When using INA219 for current detection, after the board is powered on and without load, there is a voltage of 0.12mV on Rshunt.
But about 1% to 2% of the boards, when powered on without load, have…
Part Number: INA219 Tool/software: Hi AE,
What's the purpose of the Rshunt for INA219? Can Rshunt value = 0ohm?
Besides, is there suggestion value for Rshunt? The load voltage is 12V.
Thanks a lot!
BR,
Sean Liao
Part Number: INA219 Other Parts Discussed in Thread: INA240 Tool/software: ie switching Vin+ and Vin- with 12 Volts across pins destroys the sensor! Can current ONLY flow one way?
I have smoked two sensors so far!
Part Number: INA219 Tool/software: Hi,
We have occur measure current higher than actual current.
We use PD controller to read INA219 reads ~7A, but we us current probe only measure ~5A.
But in most condition the current is normal. I've check schematic…
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…
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…
