pnp mosfet
Hi all,
I wish to be able to switch 5VDC using a mosfet. What i want to do is to be able to control the supply of 5VDC to a particular part of the circuit through an I/O from a microcontroller.
I am more familier with transistor with very little experience in FET. Can anyone recommend me common mosfet used in switching? The expected current to the isolated circuit is estimated to be around 400mA.
Is there actually any advantages in using a Mosfet as compared to using a typical pnp configuration? The only i can think of now is the voltage drop inherent in transistor.
How much more expensive is a typical mosfet as compared to a normal switching transistor?
Thanks and have a good day!
