I have a circuit design makes a button latch on-off and drive a mosfet. When I energize the circuit Vout that drives thr mosfet is initially low.
After pressing the button, the button state changes and the mosfet turns on. If I disconnect the enery from source while mosfet turn on state so "output of latch circuit is high", Vout starts from high level if I connect source again. However, if I disconnect the energy while output is low, Vout starts low if connect energy again. My design must be start always low latched when disconnect energy from circuit no mattter what Vout is.
