For the MPQ5069, the datasheet only includes one example of Rmon (10K) which is a 1.2V max-scale at 12A. What is the max voltage on IMON to maintain the linear current monitoring response?
The IMON linear voltage range is 0V to VIN-0.6V. The pin has an absolute max of 6.5V, but normal operating recommends no more than 5V. So for example, using a 20K RMON will have a ratio of 200mV/A. The max voltage will be 5V at 25A. The pin will be within limits and have linear relation as long as VIN is greater than 5.6V.
