A1699

A1699 Two-Wire, Differential, Vibration-Resistant Sensor IC with Speed and Direction Output FEATURES AND BENEFITS Integrated IC and capacitor, single overmolded package to reduce external EMI-protection requirements Two-wire, pulse-width output protocol Highly configurable output protocol options Digital output representing target profile Speed and direction information of target Vibration tolerance □□Small-signal lockout for small amplitude vibration □□Proprietary vibration detection algorithms for large amplitude vibration Air-gap-independent switchpoints Large operating air gap capability Undervoltage lockout True zero-speed operation Wide operating voltage range AEC-Q100 automotive qualified Robust test-coverage capability with Scan Path and IDDQ measurement Package: 2-Pin SIP (Suffix UB) DESCRIPTION The A1699 is an optimized Hall-effect integrated circuit (IC) that provides a user-friendly solution for direction detection and true zero-speed, digital ring-magnet sensing. The small package can be easily assembled and used in conjunction with a wide variety of target sensing applications. The IC employs patented algorithms for the special operational requirements of automotive transmission applications. The speed and direction of the target are communicated through a variable pulse-width output protocol. TheA1699 is particularly adept at handling vibration without sacrificing maximum air gap capability or creating any erroneous dire...
