UNISONIC TECHNOLOGIES CO., LTD SK8509 LINEAR INTEGRATED CIRCUIT HALL-EFFECT SENSOR IC DESCRIPTION 1 SK8509 is a semiconductor integrated circuit utilizing the Hall effect. It has been so designed as to operate in the accurately track extremely small changes in magnetic flux density-changes generally too small to operate Hall-effect switches. This Hall IC is suitable for application to various kinds of sensors, contact-less switches, motion detectors, gear tooth sensors, and proximity detectors, and the like.
