UNISONIC TECHNOLOGIES CO., LTD SK8509 LINEAR INTEGRATED CIRCUIT HALL-EFFECT SENSOR IC DESCRIPTION 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. 1 SIP-3 3 FEATURES 2 * Wide Supply Voltage Range of 4V to 7V * Wide Temperature Operation Range of -20°С ~+85°С * The Life is Semipermanent because it Employs Contactless Parts SOT-23 (EIAJ SC-59) ORDERING INFORMATION Ordering Number Lead Free Halogen Free SK8509L-AE3-R SK8509G-AE3-R SK8509L-G03-B SK8509G-G03-B SK8509L-G03-K SK8509G-G03-K Note: Pin Assignment: I: VCC O: VOUT G: GND 1 Package SOT-23 SIP-3 SIP-3 Pin Assignment 1 2 3 O I G I G O I G O Packing Tape Reel Tape Box Bulk MARKING SIP-3 www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd SOT-23 1 of 6 QW-R118-010,E SK8509 LINEAR INTEGRATED CIRCUIT BLOCK DIAGRAM REGULATOR VCC Output GND Hall Element Amplifier Control Block UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw Output Stage 2 of 6 QW-R118-010,E SK8509 LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC 7V V Supply Current ICC 10 mA Operating Ambient Temperature TOPR -20~+85 °C Storage Temperature TSTG -55~+150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
