G525A

USB High-Side Power Switch Advance Information

Features

General Description

The G525A 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

1A minimum continuous load current

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 G525A satisfies the USB standards. The switch's

low on-resistance meets USB voltage drop require-

ments. When the output load exceeds current-limit

threshold, G525A switches into constant mode and

limit the output current to a safe level, which is typi-

cally 1.4A, well below the UL 25VA safety require-

ments. An open-drain flag output is also available to

indicate fault conditions 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.

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-

high or active-low version

UL Approved_#E232223

Besides, a thermal shutdown circuit is included to pre-

vent catastrophic switch failure caused by increasing

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

The G525A is a UL recognized component and is

available in active-high and active-low versions in

8-pin SOP packages.
