A3212 - Micropower Ultrasensitive Hall-Ef?fect Switches

General Description

TheA3211 andA3212 integrated circuits are ultrasensitive, pole independent Hall-effect switches with latched digital output.

These devices are especially suited for operation in batteryoperated, hand-held equipment such as cellular and cordless telephones, pagers, and palmtop computers.

Key Features

  • AEC-Q100 automotive qualified.
  • Micropower operation.
  • Operation with north or south pole.
  • 2.5 to 3.5 V battery operation.
  • Chopper stabilized.
  • Superior temperature stability.
  • Extremely low switch point drift.
  • Insensitive to physical stress.
  • High ESD protection.
  • Solid-state reliability.
  • Small size.
  • Easily manufacturable with magnet pole independence.
