HK465 is designed and produced using CMOS technology. It is a south pole (HK465UA) or north pole (HK465SU) sensitive low-power omnipolar Hall effect switch. The device integrates a voltage regulator, a Hall voltage generator, a small signal amplifier, a chopper regulator, and schmitt-trigger and push-pull output. The sensor has the characteristics of good temperature stability, strong stress resistance and high sensitivity, and its operating voltage is 2.5-5.5V.
