A1244 Datasheet Two Wire Hall-effect Latch

Manufacturer: Allegro MicroSystems

Overview: A1244 Chopper-Stabilized, Two-Wire Hall-Effect Latch.

General Description

The A1244 is a two-wire Hall-effect latch.

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

This technique achieves magnetic stability over the full operating temperature range, and eliminates offsets inherent in devices with a single Hall element that are exposed to harsh application environments.

Key Features

  • AEC-Q100 automotive qualified.
  • 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.
  • On-board voltage regulator ▫ 3 to 24 V operation.
  • Solid-state reliability.
  • Robust EMC and ESD performance.
  • Industry-leading ISO 7637-2 performance through use of proprietary, 40 V clamping structures PACK.
