HAL® 182x

Value-Optimized Linear Hall-Effect Sensors with Fixed Sensitivity

Short Description

The HAL 182x sub-family contains factory-set members of the Micronas family of value-optimized linear Hall sensors, offering excellent performance/price trade-off. They are universal magnetic field sensors with a ratiometric, linear analog output . The members of the sensor family can be used for magnetic field measurements, current measurements and detection of any mechanical movement. Very accurate angle measurements or distance measurements can also be carried out. The sensors are very robust and can be used in harsh electrical and mechanical environments. The output voltage is proportional to the magnetic flux density through the Hall plate. The choppered offset compensation leads to stable magnetic characteristics over supply voltage and temperature.
The different family members vary by sensitivity (25 mV/mT, 31 .25 mV/mT, 29 .4 mV/ mT, and 50 mV/mT). The quiescent output voltage (offset) for all family members is 50% of the supply voltage. The sensors are designed for automotive and industrial applications and operate in the junction temperature range from –40 °C up to 170 °C.
The HAL 182x is available in the very small leaded package TO92UA and in the small SMD package SOT89B (for industrial only).
