A3250 - Chopper-Stabilized Unipolar Hall-Effect Switches

Download the A3250 datasheet PDF. This datasheet also covers the A3250_Allegro variant, as both devices belong to the same chopper-stabilized unipolar hall-effect switches family and are provided as variant models within a single manufacturer datasheet.

General Description

The A3250 and A3251 are field-programmable, chopperstabilized, unipolar Hall-effect switches designed for use in high-temperature applications.

These devices use a chopper-stabilization technique to eliminate offset inherent in single-element devices.

Key Features

  • Chopper stabilization for stable switchpoints throughout operating temperature range.
  • Externally programmable operate point (through VCC pin).
  • On-board voltage regulator for 4.2 V to 24 V operation.
  • On-chip protection against: ▫ Supply transients ▫ Output short-circuits ▫ Reverse-battery condition.
