ILC7536

Impala Linear Corporation ILC7526/7536 Final USB Dual Control Switches 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. 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 eliminates momentary upstream voltage drops when the switch is enabled, especially in bus powered applications. Additional features include undervolt...
