DESCRIPTION

The A19303 is an optimized Hall-effect integrated circuit (IC)

with PW and AK Protocol 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 and direction information with

vibration detection ideal for ABS applications.

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.
