IRF7103 and 3.3V control with STM32
Posted: Fri Jun 05, 2020 7:24 pm
I have used this solution for many years:
Mosfet does not heat up and I have no malfunction. They control 6W LED lighting per channel.
The scheme is simple, the layout is small and has few elements.
What happens if IRF7103 is controlled by 3.3V from STM32? Will this voltage be enough? Will STM32 withstand the switching current?
(unfortunately I do not have a workshop to test it right now, I have too little knowledge to deduce from technical documentation)
I am asking for help from an expert on Mosfet.
