HI

Observe in image 1, with the oscilloscope in the 50mv scale, the measurement with low noise output. It will look even better when mounted on a pcb.

I made an update of the project, inserting the indicative led (image 2)

The other part of this project, you can follow in this other topic:

Three functions for a Mosfet: CRC Filter, Soft Start and i-sense. Will it work or not
