Hello all,
on a small power supply I'm working, I've added an On Semiconductor NCS213RSQT2G high side current monitor as follows:

if I set the power supply to 12V and draw 100mA the NCS corretly outputs 0.5V (0.1Ohms * 0.1Amps * 50V/V = 0.5V)
nevertheless if I set the power supply to a different (lower voltage) and draw the same 100mA the output should still be 0.5V but it isn't and I don't understand why.
I'm supplying the NCS with more or less 15V and the Vref is tied to 0V.
can anyone help to shed light over this issue?
looking forward your reply,
Best regards, Mauro.
