Hi, I'm having a hard time with the protections mosfet, right now I'm having around 8 Volt on CHG when I connect the charger but as soon as I start charging and increase the constant current this value drop to almost -2 Volt and the N-chanel mosfet heat up.In the other hand I get zero voltage on DSG all time nothing happens there. So I would appreciate if you could give some suggestions about what I missing. But the way I have been using 30N06 as N-chanel. Thank you in advanced.
But the way I'm using the recommended circuit in page 26. But I've tried everything nothing worked.
Best Regards
Mahamud
