UNISONIC TECHNOLOGIES CO., LTD SK8552 LINEAR INTEGRATED CIRCUIT LOW VOLTAGE OPERATION HALL IC DESCRIPTION SK8552 is a semiconductor integrated circuit utilizing the Hall effect. It has been so designed as to operate in the alternating magnetic field especially at low supply voltage and operation over extended temperature ranges to +125℃.This Hall IC is suitable for application to various kinds of sensors, contact-less switches, and the like. FEATURES * Wide supply voltage range of 3V to 20V * Wide temperature operation range of -20℃~+125℃ * TTL and MOS IC are directly drivable by the output * The life is semipermanent because it employs contactless parts * Equipped with an output pull-up resistor ( typical 20kΩ) APPLICATION * Position sensor * Contact-less sensor * Detection of cover (open/close) ORDERING INFORMATION Ordering Number Package Lead Free Halogen Free SK8552L-AF5-R SK8552G-AF5-R SOT-25 SK8552L-G03-B SK8552G-G03-B SIP-3 SK8552L-G03-K SK8552G-G03-K SIP-3 Note: Pin Assignment: I: VCC O:VOUT G:GND N: No Connection www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd 1 G I I Pin Assignment 2 3 4 G O I G O G O - 5 N - Packing Tape Reel Tape Box Bulk 1 of 5 QW-R118-006,E SK8552 LINEAR INTEGRATED CIRCUIT MARKING SIP-3 SOT-25 8552 G: Halogen Free L: Lead Free BLOCK DIAGRAM Vcc REGULATOR OUTPUT CONTROL BLOCK HALL SENSOR BLOCK GND UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R118-006,E SK8552 LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS (TA = 25℃) PARAMETER Supply Voltage Supply Current Output Current RATINGS UNIT 3~20 V 10 mA 10 mA SIP-3 400 mW Power Dissipation PD SOT-25 200 mW Junction Temperature TJ +125 °C Operating Temperature TOPR -20~ +125 °C Storage Temperature TSTG -55~+150 °C Note 1.
