Each sensor in the HK54y series includes a temperature compensated Hall board with active offset compensation, a comparator, and an output driver. These sensors operate as 2-wire devices, utilizing open drain output transistors and current sources as output drivers. The function of the comparator is to compare the actual magnetic flux with a fixed reference value (switch point), causing the output transistor in the 2-wire version of the current source to activate (high current consumption) or deactivate (low current consumption).
