UNISONIC TECHNOLOGIES CO., LTD UHS49 Preliminary LINEAR INTEGRATED CIRCUIT LINEAR HALL EFFECT SENSOR DESCRIPTION UTC UHS49 Linear Hall-effect sensor is small, versatile linear Hall-effect device that is operated by the magnetic field from a permanent magnet or an electromagnet. The linear sourcing output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. The IC features low noise output, which makes it unnecessary to use external filtering. It also includes thin film resistors to provide increased temperature stability and accuracy. The linear Hall sensor can be used for Motor control, Magnetic code reading, Ferrous metal detector，Current sensing and Position sensing. 1 SIP-3 FEATURES * Low-Noise Output * 4.5 V ~ 6 V Operation * Magnetically Optimized Package * Miniature construction * Linear output for circuit design flexibility * Wide ambient temperature range: -40°C ~ +85°C ORDERING INFORMATION Ordering Number Note: UHS49G-G03-B UHS49G-G03-K Pin Assignment: I: VDD G: GND Package SIP-3 SIP-3 Pin Assignment 1 2 3 I G O I G O Packing Tape Box Bulk O: VOUT MARKING www.unisonic.com.tw Copyright © 2016 Unisonic Technologies Co., Ltd 1 of 4 QW-R118-022.b UHS49 LINEAR INTEGRATED CIRCUIT PIN DESCRIPTION PIN NO. 1 2 3 Preliminary PIN NAME VDD Supply Voltage GND IC Ground VOUT Output DESCRIPTION BLOCK DIAGRAM VDD 1 REN 3 VOUT 2 GND UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 4 QW-R118-022.b UHS49 Preliminary LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS (TA=25°С, unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC 8.0 V Circuit Current IO 20 mA Power Dissipation PD 400 mW Operating Temperature TOPR -30 ~ +125 °С Storage Temperature TSTG -40 ~ +150 °С Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
