I was wondering if there is a difference between the following switch circuits:
I simulated these here and here and they both seem to have the same behavior. The one with two FETs was suggested in BQ25505 datasheet here as a switch to disconnect the load from the power management IC.
Is there any difference between their switching speed or power dissipation?
PS: I'd appreciate any suggestions regarding the choice of the FETs in terms of low power dissipation and fast speed. The source voltage is maximum 6V (max 500mA) and the gate voltage is minimum 3V.
