Hi all,
First at all, I apoligise since I was focus in other tasks, so that I could´t reply you as soon as I expected.
I have got some results from a Pmos transistor configuration as a switch.
As reminder, I want to clarifiy that the purpose of the circuit is to switch the Mosfet on/off, which is going to be connected to an Inertial Unit (accelerometer), and this will be connected by the Vout pin. So, we are expecting the following behaviour;
1. If the switch is 'on' mode: no matter which consumption has, so it is having a properly behaviour.
2. If the switch is in 'off' mode: Regarding my results, apparently there is no current leakage, as the
multimeter shows (I indicated a micro Ampere scale into the DMM and it shows 0 value). Since the
begining a power supply was connected to the circuit, however, I decided to replace it for a
small battery in order to check if a consumption was flowing through the circuit in 'off' mode. But I
checked it out after a while, and it is having a consumption, since the Voltage has decreased. So, I
suppose it is having a current leakage.
How to avoid it?
I am using a Pmos Transistor with the following values: Rds on= 8 ohms; Vgf= 900mV. Below is linked the datasheet:

I have also enclosed you the configuration and the values used on the draw circuit.

Thank you very much and I hope this information is useful enough.
