A1245 - Two Wire Hall-Effect Latch

General Description

The A1245 is a two-wire Hall-effect latch.

The device is produced on the Allegro™ advanced BiCMOS wafer fabrication process, which implements a high frequency, 4-phase, chopperstabilization technique.

Key Features

  • High speed, 4-phase chopper stabilization.
  • Low switch point drift throughout temperature range.
  • Low sensitivity to thermal and mechanical stresses.
  • On-chip protection.
  • Supply transient protection.
  • Reverse battery protection.
  • On-board voltage regulator.
  • 3.0 to 24 V operation.
  • Operation up to 175°C junction temperature.
  • Solid-state reliability.
  • Industry-leading ISO 7637-2 performance through use of.
