The AS23xx is a housekeeping circuit for monitoring the outputs of power supplies.
It directly senses all the output rails without the need for external dividers and detects under
voltage and over
voltage.
It also provides an additional under
voltage comparator which may be configured with any arbitrary hysteresis to sense a divided ...
