BL-HE-ST3203 Omnipolar Hall Effect Switch Components

BL-HE-ST3203

Omnipolar Hall components usually refer to Hall effect switches that can detect both positive and negative magnetic polarities. When the bipolar Hall switch senses a magnetic field, the Hall effect sensor will generate a corresponding electrical signal. The characteristics of this signal (a change in voltage or current) that depends on the direction of the magnetic field, distinguishing between positive and negative magnetic polarity.

The BL-HE-ST3203 is fabricated from mixed signal CMOS technology. It internally includes an on-chip Hall voltage generator, a voltage regulator for operation with supply voltages of 1.65 to 5.5V, a sleep/awake logic for low power consumption, temperature compensation circuitry, small-signal amplifier, Hall sensor with dynamic offset cancellation system, Schmitt trigger and an open-drain output. Both south pole and north pole of sufficient strength will turn the sensor output on. The output will be turned off under no magnetic field. While the magnetic flux density (B) is larger than operating point (Bop), the output will be turned on (low), the output is held until B is lower than release point (Brp), and then turned off.

The total power consumption in normal operation is typically 15µW with a 3.3V power source. Operating temperature range of the BL-HE-ST3203 is from -40°C to 85°C.
