Product Overview
The A19302 is an optimized Hall-effect integrated circuit (IC) designed for precise speed and direction determination of sensed targets. It features a two-wire interface with optional PW or AK protocols, making it ideal for demanding automotive applications like wheel speed sensing. The compact, overmolded package integrates a capacitor and Hall-based IC, along with a lead-stabilizing bar for robust handling and assembly. Its SolidSpeed Digital Architecture ensures high accuracy in speed and rotational direction detection through intelligent algorithms that provide signal optimization and compensation, maintaining stable operation in harsh automotive environments. Developed in accordance with ISO 26262, the A19302 is a hardware safety element with ASIL B(D) capability for safety-related systems. Integrated EEPROM memory allows for device traceability throughout its lifecycle. The IC is offered in a 2-pin SIP (UB package) with enhanced EMC performance and lead-free construction.
