I am trying to charge a battery when I detect it is discharged. For this I can use a DC controlled DC relay or I can use a power mosfet that will switch on based on a signal from a GPIO(I need to realize SPST not anything fancier). Here I have a doubt regarding the gate driver to be used for the mosfet. The mosfet I use is irfiz48n. Frequency of relay toggle is 20-30Hz
My question is can I use an opamp (one of the inputs from the microcontroller and the other at 1.5v and positive source connected to 15v) to drive the gate of the MOSFET? Or do i need an elaborate gate driver.
