Hello! Please tell me the power management scheme for the microcontroller and the peripherals connected to it (shift registers 74HC595, LEDs, etc.) using the touch switch on the TTP223 chip (or another) according to the principle while the finger on the sensor is working (power is supplied to the MK). I plan to power the device from a CR2032 battery.

The TTR223 has an output to it, you put a transistor on it that turns on the relay and it already passes power to the controller and other peripherals!
