Bipolar Technology Hall Element

Latching Hall Switches

HK401

The HK401, utilizing Bipolar technology, integrates essential components on a single chip, such as a Hall element voltage generator, voltage regulator for operation within a wide voltage range (3.8 to 60V), reverse voltage protection, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and an open-collector output. This versatile sensor detects both North and South poles of a magnetic field. The HK401 comes in various package options, including TO-92 and SOT-23, all of which comply with RoHS standards.
