Hello,
I am using one of your mosfets CSD13381F4 to create a current sink in accordance with application note SLAA868. The circuit works perfectly, and I do get the current I need. However, I am using this same mosfet as well in order to switch on 5V on a resistor. You can find attached the design in the following request. The mosfet is introducing a very high voltage drop even though my current is 100mA. According to the datasheet, at 100mA, VDS should be much smaller however I am getting at least 1.5 V drop. I am not sure what is the problem.
Thank you.
Best,
ChristelleCircuitTI.TSC
