Bay Bay Linear Inspire Inspire the Linear Power Dual-Channel Power Distribution Switch B2025/2076 Advance Information 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.
