HS512 is a three-terminal Hall Effect sensor device with an output driver. The device is using

CMOS process includes an on-chip Hall voltage generator for magnetic sensing, a comparator

that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise

rejection, and push-pull output, and an internal temperature compensated circuits.

This method reduces the offset voltage normally caused by device over molding and thermal

stress.

The output is switch with either north or South Pole of sufficient strength will turn the output

on (low). The output will be turned off (high) under no magnetic field. While the magnetic flux

density (B) is larger than operate point (Bop), the output will be turned on (low); the output is

latched until B is lower than release point (Brp) and then turned off (high).

 FEATURES

? 1.65V to 5.5V battery operation

? Chopper Stabilized Technology

? Operation with North or South Pole

? High sensitivity and high stability of the magnetic switching points

? Low Profile SOT23-3L and SIP-3L(TO-92S) Packages
