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).
Core parameters and product advantages:
SOT23-3L and TO92S packaging
Typical low current consumption of 2.5mA
The working power supply voltage range is 3V to 30V
Overvoltage protection capability up to 40 V
The highest ESD performance is up to ± 12 kV
Current output for 2-wire applications
The magnetic properties are robust in the following aspects
Mechanical stress effect
Constant switching points within a wide power supply range
Voltage and temperature range
