The TDK-Micronas GmbH HAL® 54x series HAL546SF-K is a unipolar Hall effect switch offering a robust solution for magnetic sensing applications. This digital switch features an open-drain output and is supplied in a SOT-89B-1 package, suitable for surface mounting via tape and reel. Designed for operation across a wide temperature range of -40°C to 140°C, the device exhibits excellent temperature compensation. Its sensing capabilities include a typical trip point of 7.2mT and a release point of 2mT, activated by a south pole magnetic field. The HAL546SF-K operates with a supply voltage from 4.3V to 24V, drawing a maximum supply current of 4.2mA, with a maximum output current of 20mA. This component is utilized in automotive applications and industrial automation.
