The KH3106 is a medium-sensitivity Unipolar Hall-effect switch with digital latched output, special designed for automotive, industrial and consumer applications.

The KH3106 combined with a voltage regulator, Hall voltage generator, small-signal amplifier, Dynamic offset cancellation system, Schmitt trigger and open-drain output. The integrated voltage regulator permits operation from 3.5V to 24V and extended choice of temperature range. The Chopper stabilized amplifier improves stability of magnetic switch points. If the magnetic flux density is larger than operating point (BOP), the output will be turned on; if it is less than releasing point (BRP), the output will be turned off. 

The KH3106 is available in TO-92S-3 and SOT-23-3 packages which are optimized for most applications.
