Description
The G526 is a dual integrated high-side power switch
with independent enable and flag functions, optimized
for self-powered and bus-powered Universal Serial
Bus (USB) applications.
The G526 satisfies the following USB requirements:
the switch's low on-resistance meets USB voltage
drop requirements; fault current is limited to typically
750mA, well below the UL 25VA safety requirement;
and flag outputs are available to indicate fault condi-
tions to the local USB controller. Soft start eliminates
the momentary voltage drop on the upstream port that
may occur when the switch is enabled in bus-powered
applications.
Additional features include thermal shutdown to pre-
vent catastrophic switch failure from high-current loads,
under-voltage lockout (UVLO) ensuring that the device
remains off unless there is a valid input voltage pre-
sent, and an enable input that is compatible with both
3.3V and 5V logic.
The G526 is available in active-high and active-low
enable versions in 8-pin SOIC packages.
