Circuit #1) The goal is to have a circuit to give/cut power (+3.3v / +5v) to sub ICs/sensors, command by a microcontroller pin. Must cut the input voltage (circuit must be placed between VCC and IC) = high-side switch. Circuit #2) The goal is to have a circuit to enable/cut I2C bus (+3.3v / +5v), command by a microcontroller pin. We want +3.3v and +5v sensors to be connected on the same I2C bus - what about pull-up resistor ? Remarks: If power is cut (by circuit #1), power must not leak through I2C pull-up resistors. Maybe circuit #2 is not necessary if we can be sure that no current leak through pull-up resistors when cut the power.
