High Sensitivity Latching Hall-Effect Switch Sensor
The SL163X series is a low-power, latching Hall-effect switch sensor. It features an integrated temperature compensation circuit and clock logic circuit to ensure a stable operating point and switching frequency. The output latches to a low level when the applied magnetic flux density |B| exceeds the operate point |BOP|, and returns to a high level only when |B| falls below the release point |BRP|. This series supports a wide operating voltage range from 1.8V to 5.5V and is available in standard SOT-23-3L and TO-92S packages.
