I'm trying to detect small current pulses (~1.5mA). Currently I'm generating a ~20mV pulse on a sense resistor and feeding that to the input of an opAmp with some hysteresis. I'm having a bit of trouble where the output of the OpAmp will sometimes latch low and not return after the pulse passes and would like to try to use a comparator for the circuit. The problem I'm having with that is that my supply and my input are both at 6V.
Can someone recommend a good comparator that has full common mode input range with no more than 10mV of hysteresis? Or instead a better design overall?
I've found this part that seems to come close but the hysteresis might be too much.
*Based on some of the replies so far, I should mention I have a 3V3 rail available as well on the board if that helps.
EDIT: Redesigned circuit based on below suggestions- yet to evaluate
