HK50y
High Voltage Hall Effect Switch Family
Introduction
HK50y family consists of different Hall switches produced in BCDMOS technology. All Hall sensors include a temperature-pensated Hall plate with active offset pensation, a parator, and an output driver. The family consists of 3-wire devices, the corresponding output driver being an open-drain output transistor and a current source respectively. The parator pares the actual magnetic flux with the fixed reference values (switching points). Accordingly the output transistor is switched on or off in 3-wire version. The active offset pensation leads to constant magnetic characteristics over supply voltage and temperature range. In addition, the magnetic parameters are robust against mechanical stress effects.
The sensors are designed for industrial and automotive applications and operate with supply voltages from 2.7 V to 30V in ambient temperature range from -40 °C up to 150 °C.
The family AH50y is available in SOT23-3L and the leaded version TO92S packages.
