A3230 - Chopper-Stabilized Hall-Effect Bipolar Switch

Download the A3230 datasheet PDF. This datasheet also covers the A3230_Allegro variant, as both devices belong to the same chopper-stabilized hall-effect bipolar switch family and are provided as variant models within a single manufacturer datasheet.

General Description

The A3230 Hall-effect sensor is a temperature stable, stressresistant bipolar switch.

This sensor is the most sensitive Hall-effect device in the Allegro® bipolar switch family and is intended for ring-magnet sensing.

Key Features

  • Chopper stabilization ▫ Superior temperature stability ▫ Extremely low switchpoint drift ▫ Insensitive to physical stress.
  • Reverse battery protection.
  • Output short circuit protection.
  • Solid state reliability.
  • Small size.
  • Robust EMC capability.
  • High ESD ratings (HBM).

A3230 Chopper-Stabilized Hall-Effect Bipolar Switch Features and Benefits ▪ Chopper stabilization ▫ Superior temperature stability ▫ Extremely low switchpoint drift ▫ Insensitive to physical stress ▪ Reverse battery protection ▪ Output short circuit protection ▪ Solid state reliability ▪ Small size ▪ Robust EMC capability ▪ High ESD ratings (HBM) Description The A3230 Hall-effect sensor is a temperature stable, stressresistant bipolar switch. This sensor is the most sensitive Hall-effect device in the Allegro® bipolar switch family and is intended for ring-magnet sensing. Superior high-temperature performance is made possible through an Allegro patented dynamic offset cancellation that utilizes chopper-stabilization.
