| UNISONIC TECHNOLOGIES CO., LTD U18 BIPOLAR LATCH TYPE HALL-EFFECT FOR HIGH-TEMPERARURE OPERATION DESCRIPTION U18 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 FEATURES * Wide supply voltage range of 2.5V to 20V * Wide temperature operation range of -20~+125 * Alternating magnetic field operation * TTL and MOS IC are directly drivable by the output * The life is semipermanent because it employs contact less parts * SIP-3 package *Pb-free plating product number: U18L APPLICATION * Speed sensor * Position sensor * Rotation sensor * Contact-less sensor * Motor control * Built-in protection diode ORDERING INFORMATION Order Number Normal Lead Free Plating U18-G03-D-K U18L-G03-D-K Package SIP-3 Pin Assignment 1 2 3 I G O Packing Bulk Note: Pin Assignment: I:VCC O:VOUT U 1 8 L -G 0 3 -D - K G:GND (1)Packing Type (2)Pin Assignment (3)Package Type (4)Lead Plating (1) K: Bulk (2) refer to Pin Assignment (3) G03: SIP-3 (4) L: Lead Free Plating, Blank: Pb/Sn www.unisonic.com.tw Copyright (c) 2005 Unisonic Technologies Co., Ltd 1 of 6 QW-R118-007,A U18 MARKING INFORMATION LINEAR INTEGRATED CIRCUIT SIP-3 U18 L: Lead Free Plating Blank: Pb/Sn , BLOCK DIAGRAM REGULATOR Vcc Output GND Hall element Amplifier Schmidt trigger Output stage UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R118-007,A U18 ABSOLUTE MAXIMUM RATINGS LINEAR INTEGRATED CIRCUIT PARAMETER SYMBOL RATING UNIT Supply Voltage VCC 2.5V ~ 20V V Supply Current ICC 10 mA Circuit Current IOUT 20 mA Power Dissipation PD 400 mW Operating Temperature TOPR -20~+125 Storage Temperature TSTG -40~+150 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.
