ST's automotive load-dump protection devices protect sensitive semiconductors in electronic modules used for battery charging against load-dump surges when a discharged battery is disconnected from the alternator while the alternator is generating current.
Features include:
- ISO 7637-2 pulse 5A and 5B standard compliant
- Simple simulation tools to quickly secure the right device selection
Produced using automotive-grade processes and qualified to AEC-Q101, they are identified with the Y extension in the part number for the automotive version of the given protection device.
