| UNISONIC TECHNOLOGIES CO., LTD SK8552 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. LINEAR INTEGRATED CIRCUIT 1 SIP-3 3 2 1 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 * SIP-3 , SOT-25 package * Equipped with an output pull-up resistor ( typical 20k) 5 4 SOT-25 *Pb-free plating product number: SK8552L APPLICATION * Position sensor * Contact-less sensor * Detection of cover (open/close) ORDERING INFORMATION Order Number Pin Assignment Package Normal Lead Free Plating 1 2 3 4 5 SK8552-AF5-0-R SK8552L-AF5-0-R SOT-25 G G O I N SK8552-G03-D-K SK8552L-G03-D-K SIP-3 I G O Note: Pin Assignment: I:VCC O:VOUT G:GND N: No Connection SK8552L-AF5-0-R (1)Packing Type (2)Pin Assignment (3)Package Type (4)Lead Plating (1) K: Bulk, R: Tape Reel (2) refer to Pin Assignment (3) AF5: SOT-25, G03: SIP-3 (4) L: Lead Free Plating, Blank: Pb/Sn Packing Tape Reel Bulk www.unisonic.com.tw Copyright (c) 2005 Unisonic Technologies Co., Ltd 1 of 5 QW-R118-006,A SK8552 MARK INFORMATION SIP-3 8552 L: Lead Free Plating Blank: Pb/Sn , LINEAR INTEGRATED CIRCUIT SOT-25 8552 L: Lead Free Plating Blank: Pb/Sn , 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,A SK8552 ABSOLUTE MAXIMUM RATINGS (Ta = 25) PARAMETER Supply Voltage Supply Current Output Current LINEAR INTEGRATED CIRCUIT RATINGS UNIT 3~20 V 10 mA 10 mA SIP 400 mW Power Dissipation PD SOT 200 mW Junction Temperature TJ +125 C Operating Temperature TOPR -20~ +125 C Storage Temperature TSTG -55~+150 C Note 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. The device is guaranteed to meet performance specification within 0~+70 operating temperature range and assured by design from -20~+125.
