Magnetic sensors – Support & training
What are Hall effect sensors?
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 measure magnitude of magnetic fields.
- Analog and PWM output options
- Unipolar option doubles voltage swing
- Flexible Vcc, package, and sensitivity options
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.
