ILC7526/36 USB Dual Power Control Switches

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. With 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 eliminates
momentary upstream voltage drops when the switch is
enabled, especially in bus powered 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.
