Additional Details

The SI7288DP Hall Effect Latch sensor operates by sensing the presence of a magnetic field perpendicular to its sensing surface. When the magnetic field exceeds a certain threshold, the output switches state and remains in that state until a magnetic field of opposite polarity exceeds another threshold. The datasheet provides detailed information on the operating characteristics, magnetic sensitivity, and temperature performance of the sensor. Proper placement of the sensor relative to the magnetic source is crucial for optimal performance.
