跳绳测速全极霍尔HS512，兼容253

        HS512 is a three-terminal HallEffect sensor device with an output driver. The device isusing 

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

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

rejection, and push-pull output, and an internal temperaturecompensated circuits.

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

stress.

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

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

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

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

 FEATURES
