Second AC input to the full- wave bridge rectifier.
This pin is not connected on the MAX611.
Negative output terminal. This terminal is also an AC input for the half-wave rectifier of the MAX611.
The open-drain pin goes low during undervoltage and overvoltage conditions. The undervoltage and
overvoltage thresholds are fixed at 4.65V (undervoltage) and 5.4V (overvoltage) and do not change,
even if the output voltage is changed via the V
Current-limit input. The output short-circuit current limit is 0.6V/R

Positive regulated DC output.
AC input to the internal diode rectifier
An external capacitor connected to the Reset Delay pin determines the Reset Delay period. The
reset time delay is directly proportional to the capacitance connected to this pin; each 0.01µF of
capacitance results in 30 milliseconds of delay. This delay period must elapse before the Reset/OUV
pin goes high after an overvoltage or undervoltage condition (Figure 9).
