FEATURES AND BENEFITS

The A19302 is an optimized Hall-effect integrated circuit (IC)

with the option for PW- or AK-protocol two-wire interface,

ideal for applications requiring 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 SolidSpeed Digital Architecture provides highly

accurate speed and rotational direction detection. The intelligent

algorithms provide signal optimization and compensation

capable of maintaining stable operation in the harsh automotive

environments common to wheel speed applications.

The A19302 was developed in accordance with ISO 26262

as a hardware safety element out of context with ASIL B(D)

capability for use in automotive safety-related systems when

integrated and used in the manner prescribed in the applicable

safety manual and datasheet.

Integrated EEPROM memory allows traceability of the device

throughout the product lifecycle.

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.
