9 Application Information
Reset Output
The AS1923 RESETN output is asserted low when any of the monitored IN x voltages drop below its specified reset threshold (above for -5V
option) and remains asserted for the duration of the reset timeout period (120ms minimum) after all inputs have stabilized ( Figure 11 ).

The AS1923B output driver is driven by an internal 10μA current source pullup resistor. For most applications there is no need for an external
pullup resistor to interface with other logic supplies.
Note: An external pullup resistor must not be connected to the AS1923B.
The AS1923A supports an external pullup resistor to any voltage from 0 to +5.5V if interfaced to non-standard logic supply voltages (see Figure
