Hi All,
I want to switch on / off a 1A load, so using P-Channel Mosfet and gate is connected to 3.3V MCU .
When MCU sends Gate = 1 Mosfet is OFF.
MCU sends Gate = 0 Mosfet ois ON.
Here source is connected to +5V so when GATE = 0 the load is suppose to be on and should get +5V and current flow of 1A to it.
i have doubt on switching on mosfet using MCU, ( Gate = 0) is there any thing i should take care.
VGS is suppose to be -ve , i am using only 5V, 3.3V
How i am suppose to select p chaneel mosfet with these requirement
