| UNISONIC TECHNOLOGIES CO., LTD SK1816 BIPOLAR LATCH TYPE HALL EFFECT FOR HIGH-TEMPERATURE OPERATION DESCRIPTION The UTC SK1816 is a semiconductor integrated circuit utilizing the Hall effect. It designed 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, such as Speed sensor, Position sensor, Rotation sensor, Contact-less sensor, and Motor control. LINEAR INTEGRATED CIRCUIT 1 SIP-3 3 2 1 SOT-23 FEATURES * Wide supply voltage range of 2.5V to 20V * Wide temperature operation range of -20~+125 * Alternating magnetic field operation * Built-in protection diode * TTL and MOS IC are directly drivable by the output * The life is semipermanent because it employs contact-less parts * SIP-3 and SOT-23 package are available. *Pb-free plating product number: SK1816L ORDERING INFORMATION Order Number Normal Lead Free Plating SK1816-AE3-4-R SK1816L-AE3-4-R SK1816-G03-D-K SK1816L-G03-D-K Package SOT-23 SIP-3 Pin Assignment 1 2 3 O I G I G O Packing Tape Reel Bulk Note: Pin Assignment: I:VSS O:VOUT SK1816L-AE3-4-R G:GND (1) K: Bulk, R: Tape Reel (2) refer to Pin Assignment (3) AE3: SOT-23, G03: SIP-3 (4) L: Lead Free Plating, Blank: Pb/Sn (1)Packing Type (2)Pin Assignment (3)Package Type (4)Lead Plating www.unisonic.com.tw Copyright (c) 2005 Unisonic Technologies Co., Ltd 1 of 7 QW-R118-004,A SK1816 MARKING INFORMATION LINEAR INTEGRATED CIRCUIT SIP-3 1816 L: Lead Free Plating Blank: Pb/Sn , Date Code SOT-23 1816 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 7 QW-R118-004,A SK1816 ABSOLUTE MAXIMUM RATINGS (Ta = 25) PARAMETER LINEAR INTEGRATED CIRCUIT SYMBOL VCC ICC IO RATINGS UNIT Supply Voltage 2.5~20 V Supply Current 10 mA Circuit Current 20 mA SIP-3 400 Power Dissipation PD mW SOT-23 200 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.
