Greetings,
I could not find app note on INA214 precision high side current measurement so I used calculation example from SBOA300–June 2018 document. I wanted to know if TI can verify both I can use these guidelines (calculations) from low side document and that my calculations on attached writeup is OK. Basically I have +/-5A, VSS=3.3V so needed to decide what voltage reference, gain (ie INA21x device) and sense resistor to use. I came up with 1.8V reference, 0.002 ohm sense resistor and gain=100 to obtain 0.8V-2.8V output.
Also, is there any hysteresis with these devices when setting reference to midscale?
Thanks in advance.
