ILC7526/7536

USB Dual Control Switches

General Description

Features

The ILC7526 contains dual high side power control

switches, with independent enable and flag functions,

integrated into a single 8-pin SOIC package. With just a

few external components, the ILC7526 can be easily con-

figured to meet requirements for either self powered or

bus powered USB (Universal Serial Bus) applications.

The ILC7526 has active high ENABLE inputs, while the

ILC7536 ENABLE inputs are active low.

• 2 independent switches with ENABLE and FLAG

• 500mA continuous load current per switch (channel)

• 140mΩ maximum R_DSON(switch on-resistance)

• 1.25A maximum short circuit current limit

• Thermal shutdown

• 110µA typical on-state supply current

• 0.75µA typical off-state supply current

• 2.4V typical undervoltage lockout

• 2.8V to 5.8V input voltage range

• 1 ms turn-on (soft-start)

With a maximum R_DSONvalue of 140mΩ per switch, the

USB voltage drop requirements can be achieved. Each

switch can also supply up to 500mA, with internal circuitry

limiting the fault current to 750mA. Fault conditions are also

reported to the USB controller via one of the independent

flag pins. Internal circuitry provides a soft-start that elimi-

nates momentary upstream voltage drops when the switch

is enabled, especially in bus powered applications.

• Fast turn-off

• Outputs can be forced higher than inputs (off-state)

• USB specification compliant

• Active-high or active-low ENABLE versions

• 8-pin SOIC or 8-pin mini-DIP packages

Applications

Additional features include undervoltage lockout (2.4V),

fast turn-off, 2.8V to 5.8V input voltage range, thermal

shutdown to prevent switch failure from high current loads,

and 3.3V and 5V logic compatible enable inputs.

• USB host and self powered hubs

• USB bus-powered hubs

• USB monitors, printers, cameras and other USB

controlled peripherals

• Hot plug-in power supplies

The ILC7526 and ILC7536 are available in both 8-pin SOIC

and 8-pin mini-DIP packages.

• Battery charger circuits
