Package Information
Description
The Bay Linear B2526 is a dual high-side power switch
recommended for self-powered and bus-powdered universal
serial for bus (USB) application conforming to USB
requirements. USB voltage drop requirements, fault current
limited to 750mA, flag output to indicate fault connections to
the local USB controller are features that meet USB
requirements.
Additional features such as thermal shutdown to prevent
catastrophic switch failure from excessively high current
loads, under voltage lockout (UVLO) to ensure that the device
remains off unless there is a valid input voltage present, and
3.3V or 5V logic compatible enable inputs. Two versions of
the enable pin, Active High or Active Low are available in 8-
pin Dip and 8-pin SOIC packages.
