STEF4SPUR

Electronic fuse for 3.3 V and 5 V lines

ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2
GradeIndustrial
Package NameDFN10 3X3

The STEF4S is an integrated electronic fuse optimized for monitoring the output current and the input voltage. It can be connected in series to 3.3 V or 5 V rails, protecting the electronic circuitry on its output from overcurrent and overvoltage. The operating mode (5 V or 3.3 V) can be selected...
