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 RDSON (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 RDSON value 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
