High Voltage Hall Efect Switch Family

Latching Hall Switches

HK50y

The HK50y Hall switch family, using BCDMOS tech, features 3-wire devices with temperature-compensated Hall plates, active offset compensation, comparators, and output drivers. They maintain magnetic reliability across voltage and temperature variations, even under mechanical stress. Ideal for industrial and automotive applications, they work from 2.7V to 30V, handle temperatures from -40°C to 150°C, and come in SOT23-3L and TO92S packages.

Core Parameters & Product Advantages

SOT23-3L and TO92S packages

Low current consumptions of typ. 2.5 mA

Operates from 2.7 V to 30 V supply voltage

Overvoltage protection capability up to 40 V

Highest ESD performance up to ± 12 kV

Short-circuit protected open-drain output and thermal shut down for 3-wire applications

Magnetic characteristics are robust regarding mechanical stress effects

Constant switching points over a wide supply voltage and temperature range
