Automotive Electronics
AEC-Q101 / AEC-Q100 qualified components for ECUs, ADAS, infotainment, and 12V / 48V systems
Magnias supplies automotive-qualified ICs and discretes that meet the harsh thermal, EMC, and reliability requirements of vehicle electronics. Our portfolio covers load-dump and ESD protection on every external interface, low-noise LDOs and high-efficiency bucks for ECU and sensor rails, AEC-Q101 MOSFETs across the 12V to 200V class, and signal-domain ICs for diagnostic and management buses. Parts with the -A suffix are AEC-Q101 qualified; -H suffix variants are halogen-free for green-supply-chain customers.
Application areas
