Hi Patrick,
Thanks so much for your help. I still have some questions about the current sensing amp as below:
Q1. For INA226, as you said, we should use Vsense max value(81.92mV)/I load max value to
calculate the Rshunt, correct?
Q2. If my above…
Ghiran,
These requirements will be challenging to meet. Regarding the supply voltage, does the supply simply need to exist in this range, or does the part HAVE to have high voltage capability? An main advantage of a current shunt amplifier is that the…

Part Number: INA240 Other Parts Discussed in Thread: INA199 , Hello team ,
my customer Schneider is looking for selecting a current sense amplifier for high side current measurement .
the switching frequency is @ 20Khz ,
and current levels are around…
Maks,
Thank you for choosing TI. I've reviewed the data sheet and you are correct. The land pattern is missing from INA190 data sheet. That is an oversight on our part, and I will make sure that is corrected as soon as possible. In the mean time you…
Devayani,
Unfortunately it's not so objective to "solve the system," as there are several other care-abouts that I would need to know to do this. For example, do you need the output to be analog or digital? Do you need reaction hardware, such as comparators…
Aman,
INA199 is a Current-Shunt Monitor that is meant to be used to measure very high current levels at tens of amperes, or higher, in which case its input bias current, IB, of 28uA may be neglected - see below.
However, since in your case you…
Moreover, I tried using an INA199 to monitor the current. I connected the Output of the INA199 to the FB input of the TPS54200 so that it will force the voltage reference at the Vout of the INA and as such imposing the current on the Rshunt (between IN…
