Hey guys! I am creating a latch circuit which on long press will power ON and OFF my 3v3 MCU. This is very usual in many devices and power consumption is minimal. I dont want to implement it in deep sleep mode and my hardware does not include timer 555 IC. I have seen latch circuit which power ON on long press but they do not power OFF on long press. I could not debug them to achieve my functionality.....I hope anyone reading it will acknowledge my query thanks
This is the circuit i tried to modified using RC circuit( for approx 3 sec delay) before push button but perhaps i am making a mistake
