A3242 - Chopper-Stabilized Unipolar Hall-Effect Switches

Download the A3242 datasheet PDF. This datasheet also covers the A3241 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 A3241 and A3242 integrated circuits are unipolar Halleffect switches with digital outputs.

These devices are suited for operation over extended temperature ranges, up to +150°C.

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) Packages: 3 pin SOT23W (suffix LH), and 3 pin SIP (suffix UA).
