Question
What exactly is V_drop in the STP16DPPS05 datasheet?
I'm evaluating the use of STP16DPPS05 in my LED driving application.
I'd like to drive two LEDs (wired in series) per channel at 5mA. The LEDs have a worst case forward voltage drop of 1.6V each. I intend to power the LEDs and the STP16DPPS05 with a 3.3V supply.
This means that I could be asking the STP16DPPS05 to regulate the current through its output pin to 5mA at 0.1V (=3.3-2*1.6). Can it do that?
Is the V_drop table and graph on page 15/36 of the STP16DPPS05's datasheet
( https://www.st.com/resource/en/datasheet/stp16dpps05.pdf ) showing me that the part can regulate 5mA of current through my LEDs down to an output pin voltage of 71mV with a 3.3V supply?
