Vasanth,
Please correct me here, but is your high-side/common-mode voltage +48V or -48V? Just so I'm clear.
Anyway, I would recommend a shunt resistor of 16.2 mOhm. I calculated this with the following:
Vs = 10V
Current = 0 to 30A
Max Vout = {Vs…

We are using INA 193 current sensor for a battery charging application. We are using it for 24V as well as a 48 V…
Dear Kuramochi,
I am looking at this with my team right now and will get back to you with a recommendation. Thank you for all of your information.
What is the common-mode voltage (Vcm) of your system? Basically since this is a high-side application, what…
Other Parts Discussed in Thread: INA270 Dear all,
How should we think about total gain error over 100[mV]?
Now, we can read +/-2% at Vsense = 20~100[mV].
Concretely, how value of total gain error at Vsense = 300[mV] at Ta = -40~125C?
Best regards,
Ben,
The difference between Version A and Versions B and C are the internal ESD protection diodes and their structure. The internal component of the Version A device that will latch up during a high-voltage transient is not present in the B and C versions…

Other Parts Discussed in Thread: INA270 , TIPD135 , TIPD104 Dear sirs,
For customer current sensing request, which current shunt should I suggest?
Since whole system powered by 3.3V, the current shunt Vout cannot exceed 3.3V!
My original suggestion is INA270…
Hello Eli,
Thanks for your inquiry. Yes, we do have current shunt monitors that can handle a 40V common-mode voltage. They include the INA168/9 (current output), INA170 (current output), INA193-8 family, INA270-1, and the INA282.
Properly sizing…
Hi,
yes, i have one little question about this solution. I have not understand, in your reply, if you have considered correctly the powering of system. I try to send you the schematics about the connection wich i go to make in the real circuit. (Sorry…
