Allegro MicroSystems A3240LLT is a unipolar Hall effect switch featuring an open-collector output. This digital switch is designed for operation with a supply voltage range of 4.2V to 24V and a maximum output current of 25mA, with a quiescent supply current of 6mA. The device exhibits a typical sensing range with a 5mT trip point and 5mT release point, activated by the south pole of a magnetic field. Packaged in a SOT-89-3 (TO-243AA) surface-mount configuration, the A3240LLT operates reliably across an extended temperature range of -40°C to 150°C. This component is commonly utilized in automotive, industrial, and consumer electronics applications requiring precise magnetic field detection and switching, such as proximity sensing and speed detection.
