Hall switch integrated sensor characteristic curve circuit diagram

Operating characteristics of Hall switch integrated sensor

The operating characteristic curve of the Hall switch integrated sensor is shown in the figure. It can be seen from the operating characteristic curve that the operating characteristic has a certain hysteresis BH, which is very beneficial to the reliability of the switching action. Bop in the figure is the magnetic induction intensity at the operating point "on", and BRP is the magnetic induction intensity at the release point "off".

The operating characteristic curve of the Hall switch integrated sensor reflects the relationship between the external magnetic field and the sensor output level. When the external magnetic induction intensity is greater than Bop, the output level changes from high to low, and the sensor is in the on state. When the external magnetic induction intensity is less than BRp, the output level changes from low to high, and the sensor is in the off state.

The SL3075 Hall switch integrated sensor is a bistable sensor, also known as a lock-key sensor. Its operating characteristic curve is shown in the figure. When the applied magnetic induction intensity exceeds the operating point, its output is in a conductive state. After the magnetic field is removed, the output remains unchanged, and a reverse magnetic field must be applied and pushed past the release point to turn it off.
