algorithms, maintaining pitch accuracy during dynamic
air gap disturbances
• ASIL B rating based on integrated diagnostics and
certified safety design process
• User-accessible EEPROM for device traceability
DESCRIPTION
The A19300 is an optimized Hall-effect integrated circuit (IC)
that provides a user-friendly two-wire solution for applications
where pitch accuracy is important for 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 offers intelligent
algorithms capable of maintaining stable operation during
dynamic air gap movements. The sophisticated digital controller
provides highly accurate speed detection and rotational direction
detection ideal for ABS applications.
Integrated diagnostics are used to detect an IC failure impacting
output protocol accuracy, providing ASIL B compliance. The
IC includes built-in EEPROM scratch memory available for
device traceability throughout sensor module production.
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
