Product Description
Product Overview
The A19303 is an optimized Hall-effect integrated circuit (IC) designed for applications requiring precise speed and direction determination. It offers a user-friendly two-wire solution with PW and AK protocols, suitable for scenarios where pitch accuracy is critical. The IC features a compact, overmolded design integrating a capacitor and Hall-based IC, along with a lead-stabilizing bar for robust handling and assembly. Its SolidSpeed Digital Architecture employs intelligent algorithms to maintain stable operation during dynamic air gap movements, providing highly accurate speed and direction information with vibration detection, making it ideal for ABS applications. Built-in EEPROM allows for device traceability throughout sensor module production. The A19303 is available in a 2-pin SIP package (UB) that integrates a high-temperature ceramic capacitor for enhanced EMC performance. The package is lead (Pb) free with tin leadframe plating.
