Hi all,
I am using MOSFET NDS356AP[P-type] in my circuit for switching. I am using 3.6 V supply to uc and the same voltage to switch the MOSFET.
The problem I am facing here is that when the Vcc, that I want to switch, is more than 4.5V, the switching is not happening properly. When the Vcc voltage crosses 4.5 V, the MOSFET is not switching off. But when I increase the control voltage accordingly, the MOSFET switches off. i.e. when the input Gate voltage increases, the MOSFET switches off.
As I am using the uc supply as 3.6 V, I cannot increase this Gate supply. Please help to solve this issue.
