INA236: INA236 Power limit

SQUARE SQUAER

Part Number: INA236

Hello,

I plan to measure current, voltage and power using the INA236 integrated circuit. I read the datasheet, but I could not find the maximum power limit that the integrated circuit can measure. Can you give me information about this subject?

HI Square,

There really isn't a limit on what the INA236 can measure because of how our current shunt monitors work. Our devices basically measure the voltage drop across a small shunt resistor to calculate the current in that loop. The power dissipation rating of the resistor is the limiting factor, because there isn't a large amount of current flowing into the package of the INA236. You can learn more about our CSAs here: https://www.ti.com/lit/eb/slyy154b/slyy154b.pdf. You can also view this TIPL on how to choose a shunt resistor: https://www.ti.com/video/6076324596001. Please let me know if you have any further questions!

Best,

Mohamed
