The open-drain output allows the reset signal to be pulled up to a different voltage than the monitored rail, which is useful when the supervisor and the downstream processor run on separate supplies.
The output is open drain (open collector). This means an external pull-up resistor is required to define the reset signal's high level, and the output can be pulled up to a voltage different from the monitored rail.
