Hi

 

I am not able to understand the usage of P-FET (Q2003) in the circuit ?

I initially tought it is there for reverse voltage protection, but with R2013 , R2014 being placed across Source and Drain , I am not able to understand the usage of the FET.

 

Can some one tell me if there is a DNP for R2013/R2014  and also the need for Q2003.
