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.
