I am trying to use a N-channel MOSFET to toggle battery power going to a 5V voltage booster using the circuit shown in the attached image. Battery voltage is 3.7V and the gate voltage is 3.3V. High voltage at the gate is used to turn the power off and low is used to turn the power on (on by default using the 5K pull down resistor). The MOSFET switches as expected and I am able to toggle the boosted 5V on and off until I put a load in the 5V bus which seems to switch the MOSFET (BAT-SW in the schematic becomes grounded turning off power to the 5V booster circuit).
Here is a link for the MOSFET I am using https://statics3.seeedstudio.com/images/opl/datasheet/0440200P1.pdf
Any help or suggestion would b much appreciated!
