VNF1248FTR

High-side switch controller with STi2Fuse protection for 12 V, 24 V and 48 V automotive applications

ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2
GradeAutomotive
Package NameQFN-32L WF

The device is an advanced controller for a Power MOSFET in high-side configuration, designed for the implementation of an intelligent high-side switch for 12 V, 24 V, and 48 V automotive applications. The control IC is interfaced to a host microcontroller through a 3.3 V and 5 V CMOS-compatible SPI...
