Part Number: INA226 Tool/software: Hi Team, We were designing a VI monitor for a 200V system and came across this reference design. I had a few doubts regarding this: "The INA226 can also sense bus voltages less than 36 V. Since the bus voltage employed…
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…
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: TIDA-00528 Other Parts Discussed in Thread: INA290 , INA293 , LM5056A
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…
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…
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…
Hello Parth
Thank you for using the TI forum. You can accomplish this though either mirroring the current or sensing low side and dividing down the bus voltage. Here are a few examples:
Mirroring current (shunt on the high-side):

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…
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…
