Other Parts Discussed in Thread: INA237, INA240
We are using the mentioned P/N for current measurement with the following scheme:
The sequence we are using is pretty straight forward:
- Setting Vout2_R to 9V -> Expected result are measured by the INA220
- Setting Vout2_R to 16V -> INA220 is stop working and can be recovered only upon a power down-up sequence of the platform.
- Once we are in the transient from 9V to 16V we are experiencing the following wave form on the Vout_2:
It looks to us that the INA220 is failing to serve such voltage transient.
Are we correct?
Please let us know what we can do in order to improve the design.
