Let me pre-empt this with saying I am a self-taught hack with a very old (and nearly useless today) computer science degree. I have never designed with a P Channel Transistor before. My project is a PIC based 60V battery charger (from 12V Solar) for a 48V LiFePO4 battery pack. (Please don't question about Li battery charging - THAT part I am clear about and a BMS is in place.)
So, in order to take readings of the battery pack voltage on a Pic A/D pin, I needed to disconnect the 60V supply. Thus, the use of a P channel MosFET.
Here is that part of the circuit.
Anything majorly wrong?
Thanks everyone.
