Description

The A19303 is an optimized Hall-effect integrated circuit (IC) with PW and AK Protocol that provides a user-friendly two-wire solution for applications where pitch accuracy is important for the determination of speed and direction of the sensed target. The small package includes an integrated capacitor and Hall-based IC in a single overmolded design, with an additional molded lead-stabilizing bar for robust shipping and ease of assembly.

Key Features

  • Hall-effect technology allows ease of use for ring magnet and ferromagnetic target sensing with backbiased magnet
  • Vibration detection optimized for wheel speed applications allows for blanking of vibration on vibration with minimum delay in output recovery
  • Digital PW and AK protocol provides speed and direction information, signal integrity, and functional status
  • Integrated capacitor in a single overmolded miniature package provides greater EMC robustness
  • SolidSpeed Digital Architecture supports advanced algorithms, maintaining pitch accuracy during dynamic air gap disturbances
  • EEPROM enables traceability throughout the product life cycle PACKAGE: 2-Pin SIP (suffix UB)
