The is the simulated version of the schematic.
I have designed a protection circuit for my pcb and I would appreciate having some feedback before starting the PCB design.
The circuit is broken down as follow;
-ESD protection provided by a one channel IC
-low pass filter to suppress noise above 4.5Khz
-pmos to protect against reverse polarity
-crowbar for overvoltage protection
-current sensor which is connected to a uC ( ideally I would like the op amp to work with the PSU IN in the range 3.3v to 16v)
The maximum voltage is 16V and the minimum votlage is 3.3V.
The is the final version of the schematic
