USB Power Control Switch

Not Recommended for New Designs

Refer to MIC2025

General Description

Features

The MIC2525 is an integrated high-side power switch, opti-

mized for self-powered and bus-powered Universal Serial

Bus (USB) applications. Few external components are nec-

essary to satisfy USB requirements.

• Compliant to USB specifications

• UL Recognized Component

• 3V to 5.5V input

• 500mA minimum continuous load current per port

• 140mΩ maximum on-resistance

• 1.25A maximum short circuit current limit

• Open-drain fault flag pins

• 110µA typical on-state supply current

• 1µA typical off-state supply current

• Output can be forced higher than input (off-state)

• Thermal shutdown

• 2.4V typical undervoltage lockout (UVLO)

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

• Active-high or active-low enable versions

• 8-pin SOIC and DIP packages

TheMIC2525satisfiesthefollowingUSBrequirements:each

switch channel supplies up to 500mA as required by USB

downstream devices; the switch’s low on-resistance meets

USB voltage drop requirements; fault current is limited to

typically 750mA, well below the UL 25VA safety require-

ments; and a flag output is available to indicate fault condi-

tions to the local USB controller. Soft start eliminates the

momentaryvoltagedropontheupstreamportthatmayoccur

when the switch is enabled in bus-powered applications.

Additional features include thermal shutdown to prevent

catastrophic switch failure from high-current loads,

undervoltage lockout (UVLO) to ensure that the device re-

mains off unless there is a valid input voltage present, and

3.3V and 5V logic compatible enable inputs.

Applications

• USB hosts and self-powered hubs

• USB bus-powered hubs

The MIC2525 is a UL recognized component and is available

in active-high and active-low versions in 8-pin DIP and SOIC

packages.

• Hot plug-in power supplies

• Battery-charger circuits

For new designs, please see the MIC2025/2075.
