Part Number: TIDA-00528 Other Parts Discussed in Thread: INA229-Q1 , INA229
Hi,
i have 2 questions:
1- i was planning to use INA current sensor for 400V output but in Low-Side configuration due to common mode voltage issue. TIDA-00528 uses a more complex…
Part Number: TIDA-00528 Other Parts Discussed in Thread: INA226 Document #: TIDU849 - November 2015
1. Page 8, equation (8), it gives a PFET current of 8mA. which will result in a Vsense of 80mV (equation 9). Where did the 8mA/80mV come from? I do not…
Part Number: INA219 Other Parts Discussed in Thread: TIDA-00528 Tool/software: Hello,
I'm trying to find the AC 240v power monitor IC but i can't find it so i found the INA219 but IC max voltage rating is up to 26v So you can suggeste me with both f…
Hey Sivam,
Clemens is correct that our device needs to be on the same ground as what it is measuring. An isolated ADC is one good option. Another option if you still want to use the INA226 would be to use a digital isolator, or mirror the current to a…
Part Number: TIDA-00528 Other Parts Discussed in Thread: INA226 Hello,
I would like to use the TIDA-00528 design for a 48-200V monitoring application.
The Rz calculation from reference guide Rz <= (205-5.1) / (50uA + 25uA) = 2.66M (must be less than 2…

Dear team,
My customer are looking for 100V voltage monitoring solution for their application,
I found TIDA-00528 which is close to their spec.
Did we have 100V voltage…
Hello Emma,
Since they do not need a VBUS measurement, maybe they can sense on the low side. This way the voltage at the input pins is near 0V, so there would be no issue. If they do need a higher voltage at IN+ and IN-, then they could use either of…
Hello Stanly,
You are correct, the INA219 does not support that BUS voltage. If the INA219 is still needed, then here are a couple of design guides that can be used to to make this work:

Part Number: TIDA-00528 Other Parts Discussed in Thread: TINA-TI , INA226 , OPA333 , AMC1302 I am trying to design a circuit similar to the reference design TIDA-00528 where the bus voltage is 60V and the current to be measured is from 0.5mA to 1A. I will…
Hi Jimmy,
I missed the uA. Thank you for catching that and apologies for the mistake.
I would not use the TMCS1108 as the offset error is in the mA range and would not allow for accurate measurements in uA. We do have the new TMCS1123 with higher precision…
