Magnetic Hall effect sensors

Low power, highly reliable, cost-optimized solutions for magnetic position sensing

Known for robust durability and dependable operation, TI magnetic Hall effect sensors are the simplest solution for any position sensing application. Whether simply detecting the closing of a lid/surface or performing complex motor commutation, TI’s Hall effect sensors will reliably and accurately sense the position in any system.

Hall effect latches & switches

Hall effect switches and latches indicate the presence or absence of magnetic fields.

  • Digital output
  • Wide voltage and temperature range
  • Ultra-low power options

Linear Hall effect sensors

Linear Hall effect sensors measure magnitude of magnetic fields.

  • Analog and PWM output options
  • Unipolar option doubles voltage swing
  • Flexible Vcc, package, and sensitivity options

Latch functionality

Unipolar switch functionality

Hall effect latches require alternating north and south magnetic poles to toggle. They are used in rotary applications, whether for BLDC motor sensors or incremental encoding.

Hall effect switches indicate if a magnet is close by, based on a predefined magnetic threshold. TI offers both omnipolar and unipolar Hall effect switches.

Linear analog output

Linear PWM output

Linear hall effect sensors output a signal that's proportional to magnetic flux density for precise position measurement.
