500mA Minimum Continuous Load Current
B2076 with Circuit Breaker Mode
Logic Compatible Input
Thermal Shutdown & Short Circuit protection
Pin Compatible with B2526
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.
