Hall-effect latches & switches

Low power, high sensitivity digital Hall-effect sensors

Our digital Hall-effect sensors are known for robust durability and dependable operation for a wide variety of position sensing applications. Whether simply detecting the closing of a lid or performance complex motor commutation, Hall-effect latches & switches are simple contactless position measurement solutions.

Device type

Choose latches or switches for your design. Switches are offered with unipolar (switches on one magnetic pole) and omnipolar (reacts to both poles)

Supply voltage

Hall-effect sensors are offered with operating supply voltages to better suit your supply rail

Device packaging

Our Hall-effect latches & switches are available in several different packaging options, designed to reduce the amount of board space required for your design

Featured Hall-effect switches

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.


Ultra-low-power digital-switch Hall-effect sensors, design for the most compact and battery-sensitive systems


Chopper-stabilized Hall-effect sensor that offers a magnetic sensing solution with superior sensitivity stability over temperature and integrated protection features


Low-voltage, digital-switch, Hall-effect sensor with 2.5-V to 5.5-V power supply for sensing magnetic flux density and provides a digital output

Featured Hall-effect latches

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