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.
