L9969U-TR

Automotive chip for single and dual H-bridge

ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2
GradeAutomotive Safety
Package NamePowerSSO 36

L9969S/L9969U and L9969T are single and dual integrated H-bridges for resistive and inductive loads featuring output current direction and supervising functions.The PowerSSO24 houses one full H-bridge, while the PowerSSO36 houses both two H-bridges that can work in parallel, through independent...
