Description
The Bay Linear B2026 & B2076 are a dual high-side power
switch recommended for general Propose self-powered and
bus-powdered universal serial for bus (USB) application
conforming to USB requirements.
These devices include
thermal shutdown which in fault modes reduces the current
consumptions.
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. These
device it includes internal current limits. The 2026/76 offer a
soft-start circuit for limit the inrush current and Fault status
output flag for time over current and thermal shutdown status.
Bay Linear B2026/76 are available in 8-pin Dip and 8-pin
SOIC packages.
