For open-drain output type reset ICs, what is the state of the output when connecting the output pull-up resistor R_L to a separate power supply and turning the power supply VDD OFF?
- When VDD reaches the detection voltage the output goes to 'L', and once it drops below the operating supply voltage range V_OPL the output goes to high impedance and outputs the voltage at the pull-up location.
