Dual USB High-Side Power Switch

Description

G526

Features

ꢀCompliant to USB specifications

ꢀLow MOSFET on resistance at 5.0V 140mΩ max.

per channel

ꢀ500mA minimum continuous load current per

channel

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.

ꢀ3.0V to 5.5V input

ꢀ110µA typical on-state supply current

ꢀ1µA typical off-state supply current

ꢀOutput can be forced higher than input

(off-state)

ꢀ1.25A maximum current limit

ꢀThermal shutdown

ꢀ2.4V typical undervoltage lockout (UVLO)

ꢀOpen-drain fault flag pins

ꢀ1ms turn-on (soft-start) and fast turnoff

ꢀAvailable with active-high or active-low

enable

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.

Applications

ꢀUSB host and self-powered hubs

ꢀBus-powered hubs

ꢀHot plug-in power supplies

ꢀBattery-charger circuits

The G526 is available in active-high and active-low

enable versions in 8-pin SOIC packages.
