The BTS50080-1EGA provides embedded protective functions. Integrated protection functions are designed to
prevent IC destruction under fault conditions described in the data sheet. Fault conditions are considered as
“outside” normal operating range. Protection functions are neither designed for continuous nor repetitive
operation.
