Sensing IC for automotive applications

摘要

The A1688 from Allegro MicroSystems Europe is a Hall-effect sensor IC for true zero-speed digital ring magnet and gear tooth sensing in two-wire automotive applications such as ABS braking systems. The device performs well on pitch deviation accuracy, consistent supply current distribution (better than six-sigma), low jitter and enhanced EMC performance provided by an integrated capacitor which also reduces the requirement for external components.
