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) applications. The ILC7526 has active high ENABLE inputs, while the ILC7536 ENABLE inputs are active low.
