Hi
We are operating with VRSNS2 below 80mV, but the IMON2 voltage is saturating at 2V and will not rise to 2.5V.
Under these conditions (RSNS=11mΩ, RIN=2.2kΩ, RMON2=80kΩ), an output current (Io) of 5A results in an IMON voltage of 2V. If we increase Io from this state, the linearity deteriorates at 2.2V.
The datasheet states, "The maximum dynamic range for IMON2 is 2.5V." Is the actual usable range only up to 2V?
