Part Number: TIDA-00313 Other Parts Discussed in Thread: INA226 , INA231 Tool/software: Hi Team,
Two questions need to check with you about reference design TIDA-00313:
Can INA226 be replaced by INA231 to save board area？
After Vs and GND are…

Kindly let me know how this can be ordered. Thanks…
Part Number: TIDA-00313 Other Parts Discussed in Thread: LMP8601-Q1 , LMP8601 , INA282 Tool/software: Hi expert
I looked at your reference design and I don't want to use the current sensor of the I2C interface. I want to use Current Sensing with analog…
Part Number: INA226EVM Hello, I'm looking over the -48V Telecom Current, Voltage and Power Sense with Isolation Design and I notice that in the schematics the VBUS voltage is connected to V+ pin 10 instead of V- pin 9.

Part Number: TIDA-00313 Other Parts Discussed in Thread: INA226 After studying the TIDA-00313 schematic and filling in the blanks of how a -48V supply would be connected, it appears to me that the VBUS voltage divider current is going through the shunt…
Part Number: INA226 Other Parts Discussed in Thread: TIDA-00313 , INA186 , INA193 , Can I use INA186 or INA193 according to the topology of TIDA-00313 –48-V Telecom Current, Voltage, and Power Sense With Isolation Reference Design?
We don't need an…
Part Number: INA226 Other Parts Discussed in Thread: TIDA-00313 Tool/software: I have a design using two INA226 to measure +12V and -12V and a common ground. For negative bus, I have left the VBUS connection open, and I am trying to measure the shunt…
Hi Bhavesh, Having two different grounds is the reason for the reading mismatch, the device ground and load ground are meant to be the same so that the device measures voltage and current with reference to the common ground. You don't need separate grounds…
Hello Ahmed,
For the bus voltage you can use a transient-voltage-suppression diode. Here is an example reference design that uses one of these on the VBUS pin: https://www.ti.com/tool/TIDA-00313 . Note this design is focused for negative common modes…
Hello Chase,
I agree with Clemens, it would be better to add the isolator on the I2C signals. Here are a couple example designs that do this:

Or, you could use a device that…
