Bipolar Hall Switch AEC-Q100 Automotive Electronics

Latching Hall Switches

HK501

The HK501 family features versatile Hall switches using BCDMOS technology. These 3-wire Hall sensors offer active offset compensation, ensuring consistent magnetic performance across supply voltages (2.7V to 30V) and temperatures (-40°C to 150°C). Designed for industrial and automotive applications, they use a comparator to control an output transistor based on magnetic flux, and they are robust against mechanical stress effects. Available in SOT23-3L and TO92S packages.
