General Description

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 configured to meet requirements for either

self powered or bus powered USB (Universal Serial Bus) applica-

tions. The ILC7526 has active high ENABLE inputs, while the

ILC7536 ENABLE inputs are active low. With maximum RDS_ON

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 condi-

tions are also reported to the USB controller via one of the inde-

pendent flag pins. Internal circuitry provides a soft-start that elim-

inates momentary upstream voltage drops when the switch is

enabled, especially in bus powered applications. Additional fea-

tures include undervoltage lockout (2.4V), fast turn-off, 2.8V to

5.8V input voltage range, thermal shutdown to prevent switch fail-

ure from high current loads, and 3.3V and 5V logic compatible

enable inputs.
