A19303 Datasheet | Allegro MicroSystems

Features AND BENEFITS - 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 - Solid Speed 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) 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. The IC’s Solid Speed Digital Architecture offers intelligent algorithms capable of maintaining stable operation during dynamic air gap movements. The sophisticated digital controller provides highly accurate speed and direction information with vibration detection ideal for ABS applications. The IC includes built-in EEPROM scratch memory available for device traceability throughout sensor module production. The IC is offered in the UB package, which integrates the IC and a high temperature ceramic capacitor in a single overmolded SIP package for enhanced EMC performance. The 2-pin SIP package is lead (Pb) free, with tin leadframe plating.
