Hello Forum,
I am building a 24Volts Lead acid battery charger (28V output, 6 Amps) and have a micro which senses the battery full charge voltage and disconnects the charging current, right now i am using a relay but want to use P-channel mosfet like IRF9540 for controlling the charging voltage/current. i cannot use N-channel mosfet. and i am not using any PWM. only simple on/off
i need help as to how to turn on the P-channel mosfet without exceeding the Vgs limit, i know a 10V zener can be used but not sure how to do it for a P-ch mosfet.
Regards,
Arun
