Re: Gate driving IC for P chanel MOSFET IRF 4905
Hi,
a bit more information is needed what you want to do with that circuit. What current do you expect, what PWM frequency, what PWM duty cycle range?
***
It seems it is 5V powered. Do you want to charge the battery marked with "2V".
There is no current limiting device. I recommend to use it. Or a fast current measurement with fast switch OFF at overcurrent.
An inductor for defined current rise and as energy storage.
The V_GS_on is a bit high. You risk to come in the linear region of the FET, causing high power dissipation and maybe burn the FET.
