     Our pole-independent sensing technique allows for operation with either a north pole or
south pole magnet orientation, enhancing the manufacturability of the device. The state-of-the-art technology provides the same output polarity for either pole face.It is strongly recommended that an external bypass capacitor be connected (in close proximity to the Hall sensor) between the supply and ground of the device to reduce both external noise and noise generated by the chopper-stabilization technique. This is especially true due to the relatively high impedance of battery supplies.


 



01.The BL-HE-ST3201 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. A south 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.



02.The total power consumption in normal operation is typically 15µW with a 3.3V power source. Operating
temperature range of the BL-HE-ST3201 is from -40°C to 85°C.
