Description

The LND3526, is a dual high side power control switch, with independent enable and flag functions optimized for self powered and buspowered universal serial bus (USB) applications.

The LND3526 satisfies the following USB requirements: Each switch channel supplies up to 500mA with internal circuitry limiting the fault current to 750mA. The switch's 140m onresistance meets USB voltage drop requirements. A flag output is available to indicate fault conditions to the local USB controller.

Additional features include: lockout (UVLO) to ensure that the device remains off until there is a valid input voltage present, thermal shutdown to prevent switch failure from high current loads and 3.3V and 5V logic compatible enable inputs. The LND3526 is available in active-high and active-low versions in 8-pin die and SOIC packages.
