The AX8733 is an integrated power switch for self powered and bus powered Universal
Serial Bus (USB) applications with high output absolute rating of 28V
A built
in charge pump is used to drive the N channel MOSFET that is free of parasitic body
diode to eliminate any reversed current flow across the switch when it is powered off . FLAG is an
open drain output report over current or over temperature event and has typical 9ms deglitch
timeout period . When the output voltage/current is higher than input voltage, the power switch is
turned off by internal output reverse voltage/current comparator . Several Protection features include
current limiting and thermal shutdown to pr event catast rophic switch fail ure caused by increas ing
power dissipation when con tinuous heavy loads or short circuit occurs.
