General Description

The A119x and A119x-F comprise a family of two-wire, unipolar, Hall-effect switches, which can be trimmed by the user at end-of-line to optimize magnetic switchpoint accuracy in the application.

The latter (-F option) are temperature-compensated for use with ferrite magnets.

These devices are produced on the Allegro™ advanced BiCMOS wafer fabrication process, which implements a high-frequency, 4-phase, chopper stabilization technique.

Overview

A119x and A119x-F Programmable, Chopper-Stabilized, Two-Wire Hall-Effect.

Key Features

  • Choice of factory-set temperature coefficient (TC) for use with ferrite or rare-earth magnets.
  • Field programmable for optimized switchpoints.
  • AEC-Q100 automotive qualified ▫ On-board voltage regulator: 3 to 24 V operation.
  • High-speed, 4-phase chopper stabilization ▫ Low switchpoint drift throughout temperature range ▫ Low sensitivity to thermal and mechanical stresses.
  • On-chip protection ▫ Supply transient protection ▫ Reverse-battery protection ▫ Industry-leading ISO 7.
