Product One-Sheet
System in a package
–
Highly integrated part ideal for space-
constrained relay driven DC motors on LIN Bus
Low system cost
–
Direct connection with battery, integrated LIN
Phy, LS & HS drivers and EVDD reduce system, qualification and
manufacturing cost.
High reliability
–
High immunity to EMI and ESD stresses, LIN
2.x compliant with +/- 8 kV ESD capability.
Enablement
–
Supported by comprehensive hardware and
software solution, which reduces development costs and time-to-
market
