The TDK-Micronas GmbH HAL509SF-A is a unipolar Hall effect sensor designed for surface mounting in a SOT-89B-1 (TO-243AA, Variant) package. This digital switch features an open-drain output and is optimized for sensing the south pole of a magnetic field. With a typical operating temperature range of -40°C to 170°C (TJ), it offers robust performance across demanding environments. The device operates from a supply voltage of 3.8V to 24V, drawing a maximum supply current of 4.2mA. Its output current capability is rated at a maximum of 20mA. Key features include temperature compensation for stable operation. The HAL509SF-A is suitable for applications requiring sensitive and reliable magnetic switching, such as in automotive systems, industrial controls, and consumer electronics. The component is supplied in Tape & Reel (TR) packaging.
