G528/G528A

USB High-Side Power Switch Advance Information

Features

General Description

The G528/G528A is an integrated high-side power

switch optimized for self-powered and bus-powered

Universal Serial Bus (USB) applications.

Typical 110mΩ, Low MOSFET on resistance, at

5.0V

3.0V to 5.5V operating range

100 µA typical on-state supply current

1µA typical standby supply current

Output can be forced higher than input when

operating in off state.

The G528/G528A satisfies the USB standards. The

switch's low on-resistance meets USB voltage drop

requirements. When the output load exceeds cur-

rent-limit threshold, G528/G528A switches into con-

stant-current mode and limit the output current to a

safe level, which is typically 1.4A. An open-drain flag

output is also available to indicate fault conditions to

the local USB controller. Soft start eliminates the mo-

mentary voltage drop on the upstream port that may

occur when the switch is enabled in bus-powered

applications.

1.4A Typical current limit

Thermal shutdown protection

2.4V typical under-voltage lockout (UVLO)

Open-drain fault flag pin

Slow turn-on (soft-start) and fast turnoff

Logic level enable pin, available with active-low

version (G528), or available with active-high

version (G528A)

UL Approved_#E232223

Besides, a thermal shutdown circuit is included to

prevent catastrophic switch failure caused by increas-

ing power dissipation when continuous heavy loads or

short circuit occurs. A under-voltage lockout (UVLO)

circuit ensures that the device remains off unless there

is a valid input voltage present, and an enable input

that is compatible with both 3.3V and 5V logic.

Applications

High-side power protection switch

USB power management

USB host and self-powered hubs

USB Bus-powered hubs

Hot plug-in power supplies

Battery-charger circuits
