Product Overview
The A19300 is an ASIL-compliant Hall-effect wheel speed sensor IC designed for applications requiring accurate speed and direction detection. Its user-friendly two-wire solution integrates a Hall-based IC and a capacitor in a single overmolded package with a lead-stabilizing bar for robust handling and assembly. Featuring SolidSpeed Digital Architecture, the IC maintains stable operation during dynamic air gap movements and provides highly accurate rotational direction detection, making it ideal for ABS applications. Integrated diagnostics ensure ASIL B compliance by detecting IC failures impacting output protocol accuracy. The device includes built-in EEPROM for traceability throughout sensor module production.
