MIC2536

Dual USB Power Distribution Switch

Preliminary Information

General Description

Features

The MIC2536 is a cost-effective high-side power switch, with

two independently controlled channels, optimized for bus-

poweredUniversalSerialBus(USB)applications. Fewexter-

nal components are necessary to satisfy USB requirements.

• Compliant to USB specifications

• 2.7V to 5.5V operating range

• 150mA minimum continuous load current per channel

• 400mΩ typical on-resistance

• Fast-acting short circuit protection with

thermal shutdown

• Integrated filter eliminates

Each switch channel of the MIC2536 will supply up to 100mA

asrequiredforUSBbus-powereddownstreamdevices.Fault

current is limited to typically 275mA by fast-acting current-

limit circuitry which minimizes voltage droop on the upstream

port during fault conditions. A flag output with transient filter

indicates fault conditions to the local USB controller but will

ignore short flag signals resulting from inrush current during

hot plug-in events.

false overcurrent flag assertions

• Individual open-drain fault flag pins with transient filter

• 3V/5V-compatible enable inputs

• Active-high (-1) and active-low (-2) versions

• Reverse-current blocking in off mode (no “body diode”)

• Soft-start circuit

• 100µA maximum on-state supply current

• <1µA typical off-state supply current

• –40°C to 85°C operation

Soft start eliminates the momentary voltage droop on other

ports that may occur when the switch is enabled in bus-

powered applications. Additional features include thermal

shutdown to prevent catastrophic switch failure from high-

current loads and 3.3V and 5V logic compatible enable

inputs.

Applications

• USB keyboard bus-powered hubs

• USB bus-powered docking stations

• Note Book PCs

The MIC2536 is available in active-high and active-low ver-

sions in 8-lead SOP and MSOP.

• PDAs

• General purpose power distribution applications

• PC board hot swap

• Inrush current-limiting
