AS23xx Secondary Side Housekeeping Circuit Features Description Standard PC Power Good: UV Detection on 4 rails UV Detection of AC/Bulk supply OV Detection on 4 rails Open collector PG out Pogrammable Fault output: OV OV plus UV OV plus UV after startup delay OV Crow Bar Driver Digital ON/OFF input 2.5V Voltage Reference Operates from 5V or 12V rail 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 undervoltage and overvoltage. It also provides an additional undervoltage comparator which may be configured with any arbitrary hysteresis to sense a divided down representation of the AC bulk voltage. The housekeeping section provides all the features necessary to allow external caps to set the common timing features of PC type power supplies. In addition, negative rails may be sensed without the necessity of a VEE connection, and negative s...
